Two cannonballs, A and B, are fired from the ground with identical initial speeds, but with A larger than 0B.- (a) Which cannonball reaches a higher elevation? (b) Which stays longer in the air? (c) Which travels farther? Explain.

Please answer this with in 30 mins ! I will upvote ! Question: A Boston Red Sox player hits the ball at a 15 degree angle with an initial speed of 145 feet per second. The bat is 3 feet from the ground at the time of impact. The "Green Monster, the left field wall in Fenway Park, is 315 feet from home plate How high will the ball be in feet when it reaches the wall? Round to the nearest hundredth

A supply plane flies horizontally with a speed of 100 m/s and an altitude of 350 m. Use g = -10 m/s/s. A) What are the initial velocity components of an object that is dropped from the plane at the instant it is dropped? B) How fast is an object that is dropped from the plane traveling 7.5 seconds later?  C) What angle, below the horizontal, does the velocity vector of an object that is dropped from the plane make 7.5 seconds later?  D) How long does it take for an object that is dropped from the plane to hit the ground when air resistance is neglected?  E) How far does an object that is dropped from the plane travel in the horizontal direction?

6. A ball is thrown upward with a velocity of 4.5 m/s. Its speed and the magnitude of its acceleration at the highest point (a) are both equal to zero (b) are given by 9.81 m/s and 0 m/s², respectively (c) are given by 0 m/s and 9.81 m/s², respectively (d) cannot be predicted unless the height is known Answer: 7. Which of the following statements about a projectile is not true? Assume that the air resistance is negligible. (a) Its motion is in two dimensions. (b) The only acceleration is in the vertical direction. (c) Its velocity in the horizontal direction remains the same throughout the flight. (d) The velocity at the highest point of its trajectory is zero. Answer:

4) You launch a ball upwards at a velocity of 10 m/s from a height of one meter. a)How high does the ball reach above the ground? b)How long does it take to hit the ground? You launch a ball upwards at a velocity of 7 m/s from a height of 1.6 meter. a)How high does the ball reach above the ground? b)How long does it take to hit the ground?

A projectile is fired from point A at the edge of a cliff, whose initial velocity components are v0x = 60.0m / s and v0y = 175m / s. The projectile rises and then falls into the sea at point P. The projectile flight time is 40.0s and it does not experience appreciable air resistance in flight. a) Make a diagram of the problem, b) Determine how far it falls, c) what is the height of the cliff? and d) at what angle was it shot?

A certain volcano on the Earth can eject rocks vertically to a maximum height H. How high (in terms of H) would these rocks go if a volcano on a planetary object ejected them with the same initial velocity? The accelerations due to the gravity on the Earth and the planetary object are 9.8m/s² and 3.1 m/s?, respectively. Neglect the effect of the air on both planets. 답:
