A high-performance jet plane, practicing radar avoidance maneuvers, is in horizontal flight 40.0 m above the level ground. Suddenly, the plane encounters terrain that slopes gently upward at 3.90°, an amount difficult to detect (see the figure). How much time does the pilot have to make a correction to avoid flying into the ground ( s)? The speed of the plane is 1200 km/h.

A father demonstrates projectile motion to his children by placing a pea on his fork's handle and rapidly depressing the curved tines, launching the pea to heights above the dining room table. Suppose the pea is launched at 7.39 m/s at an angle of 73.0° above the table. With what speed (in m/s) does the pea strike the ceiling 2.10 m above the table? HINT Use the kinematic equations to find the x- and y-components of the pea's velocity when it hits the celing. Then use the Pythagorean theorem to find the speed.

Emily throws a soccer ball out of her dorm window to Allison, who is waiting below to catch it. Emily throws the ball at an angle of 30° below horizontal with a speed of 12 m/s, and Allison catches it 2.5 s later. How far from the base of the dorm does Allison stand to catch the ball, in meters? Use g = 10.0 m/s2.

Please do help me with this please. It is a physics question. Please, i promise to give a perfect feedback to you.

ment Chapter 04, Problem 039 Your answer is partially correct. Try again. In the figure, a ball is thrown leftward from the left edge of the roof, at height h above the ground. The ball hits the ground 1.80 s later, at distanced = 26.0 m from the building and at angle 0 = 56.0° with the horizontal. (a) Find h. (Hint: One way is to reverse the motion, as if on videotape.) What are the (b) magnitude and (c) angle relative to the horizontal of the velocity at which the ball is thrown (positive angle for above horizontal, negative for below)?

A baseball pitcher throws a pitch with an initial velocity of 45 m/s (100 mph!), directed horizontally. You will be asked to find how far the ball drops vertically by the time it crosses the plate 18.0 m away.  Find the time it takes for the ball to travel the horizontal distance to the plate.    2.5 s   0.40 s   4.6 s   0.22 s

A fly ball is hit to the outfield during a baseball game. Let’s neglect the effects of air resistance on the ball. The motion of the ball is animated in the simulation (linked below). The animation assumes that the ball’s initial location on the y axis is y0 = 1 m, and the ball's initial velocity has components v0x = 20 m/s and v0y = 20 m/s. What is the initial angle (in degrees) of the baseball's velocity? (Write only the numerical value of the answer and exclude the unit) Blank 1

A ball is thrown vertically upward with an initial speed of 88 ft/sec from the base A of a cliff with H = 60 ft. Determine the distance h by which the ball clears the top of the cliff and the time t after release for the ball to land at B. Also, calculate the magnitude of the impact velocity vg. Neglect air resistance and the small horizontal motion of the ball. Answers: h = i ft t = i sec VB = i ft/sec

After flying for 20 min in a wind blowing 39 km/h at an angle of 22° south of east, an airplane pilot is over a town that is 60 km due north of the starting point. What is the speed of the airplane relative to the air?

A projectile is launched with an initial velocity 38 m/s and an angle from the horizontal of 45°. The acceleration due to gravity is 9.81 m/s². Assume the projectile is launched from the surface of the Earth. i.e., at y (0) = 0. then the altitude of the projectile as a function of time is: y(t) = gt² + vo sin(0)t Where vo is the initial velocity. What is the maximum altitude achieved by the projectile?
