A bomber is flying horizontally over level terrain at a speed of 265 m/s relative to the ground and at an altitude of 2.90 km. (a) The bombardier releases one bomb. How far does the bomb travel horizontally between its release and its impact on the ground? Ignore the effects of air resistance. ? km (b) Firing from the people on the ground suddenly incapacitates the bombardier before he can call, "Bombs away!" Consequently, the pilot maintains the plane's original course, altitude, and speed through a storm of flak. Where is the plane relative to the bomb's point of impact when the bomb hits the ground? ?ahead of the bomb ?directly above the bomb    ?behind the bomb (c) The plane has a telescopic bombsight set so that the bomb hits the target seen in the sight at the moment of release. At what angle from the vertical was the bombsight set? ? ° forward from the vertical

A 35-kW freight elevator with a total mass of 1950 kilograms rises to a height of 25 metres in 32 seconds. What is the efficiency of the elevator? 45% 43% Option 2 Option 4 46% 44% Option 1 Option 3

A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of 17.0 m/s. The cliff is h = 51.0 m above a flat horizontal beach, as shown in the figure below. How long after being released does the stone strike the beach below the cliff? (s) With what speed and angle of impact does the stone land?      ( m/s)      ( ° below the horizontal)

An athlete in a high jump event is running at 5.3 m/s directly toward the high-jump bar when he jumps into the air to jump over the bar. He maintains his horizontal velocity. (Hint : The athlete is now on a projectile trajectory to reach the high-jump bar) (a)What vertical velocity (in m/s) does he need in order to just rise 65 centimeters above the ground? (b)How far (in m) from the bar (measured in the horizontal direction) must he start his jump to reach his maximum height at the same time as he reaches the bar?

During a recent winter storm, bales of hay had to be dropped from an airplane to a herd of cattle below. Assume the airplane flew horizontally at an altitude of 185 m with a constant velocity of 44.0 m/s and dropped one bale of hay every 4.0 seconds. It is reasonable to assume that air resistance will be negligible for this situation. About how far apart from each other will the bales land on the ground?

A batter hits a baseball 3 ft above the ground, so that the ball leaves the bat with a speed of 120 ft/s and at an angle 60° above horizontal. (a) How far will the baseball travel until it first hits the ground? (b) What will be the maximum height of the baseball? (c) What is the speed that the baseball is traveling at when it first hits the ground?

Problem 1 ( . You are on one bank of a river at height h want to jump across the river to the opposite bank, which is at the same height as the river horizontal distance d = 1.5 m away. = 2m above the river. %3D d (a) If you leave the bank of the river at an angle 0 = 30°, what initial speed do you need to just barely make it to the other side? (b) If you jump at this angle and with the speed you found in (a), what is your speed just before you land on the other side of the river? (c) Suppose that when you land on the other side of the fiver, an average force of 14 000 N brings you to rest. Assuming all of this force is exerted on your tibia, what is the percent change in the length of your tibia as you are landing? Assume the tibia has a cross-sectional area of 3 cm? and a Young's modulus of 1.4 x 1010 Pa.

a student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of vo=18,5 m/s. the cliff is h=49.0 m above a flat, horizontal beach. this is a sub-par solution.  (e) How long after being released does the stone strike the beach below the cliff. give answers in seconds?. (f) with what speed and angle of impact do the stone land?  vf= in m/s 0= degree below the horizontal ( give answers in that form)

At a particular instant, a hot air balloon is 50.3 m above a horizontal field and descending at a rate of 3.5 m/s. At this instant, a girl throws a ball horizontally (relative to herself) with an a speed of 12.3 m/s. When the balloon lands on the ground, how far is she from where the ball landed? Express your answer in meters and neglect air resistance.

A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v0 = 17.5 m/s. The cliff is h = 32.0 m above a flat, horizontal beach as shown in the figure. (a) What are the coordinates of the initial position of the stone? x0     m y0     m (b) What are the components of the initial velocity? v0x     m/s v0y     m/s (c) Write the equations for the x- and y-components of the velocity of the stone with time. (Use the following as necessary: t. Let the variable t be measured in seconds. Do not include units in your answer.) vx   vy   (d) Write the equations for the position of the stone with time, using the coordinates in the figure. (Use the following as necessary: t. Let the variable t be measured in seconds. Do not state units in your answer.) x   y   (e) How long after being released does the stone strike the beach below the cliff? (f) With what speed and angle of impact does the stone land? vf    m/s θ…
