Answer this question

In the horizontal shooting test, if the height of the ball ejected from the assembly is y = 0.25m and the distance it travels in the horizontal is x = 0.65m, what is the launch speed (m / s) of the ball?

A student throws a heavy red ball horizontally from a balcony of a tall building with an initial speed vo. At the same time, a second student throws a lighter blue ball horizontally from the same balcony with an initial speed vo/2. Ignoring air resistance, which of the following statements must be true? [There may be more than one correct answer.] Both balls hit the ground with the same angle of impact. Both balls hit the ground with the same vertical velocity component While each ball is in the air, the red ball has the greater magnitude of acceleration. The red ball hits the ground with the greater speed. | The balls reach the ground at the same instant.

A person on the top of a roof of a building (100 m) drops a ball. After 2s passed, a person who stands at the base of the same building throws a separate ball in the upward direction with a speed of 20 m/s. Assumes the two balls are traveling on the same vertical path. Will the two balls collide with each other? If so, what are their velocities as they collide with each other?

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 180 m with a constant velocity of 50 m/s and dropped one bale of hay every two 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? 300 m O 180 m O 100 m 50 m

2. An archer standing on the back of a pickup truck moving at 28 m/s fires an arrow straight up at a duck flying directly overhead. He misses the duck. The arrow was fired with an initial vertical velocity of 49 m/s relative to the truck. (a) For how many seconds will the arrow be in the air? (b) How far will the truck travel while the arrow is in the air? (c) Where, in relation to the archer, will the arrow come down? (Ignore air friction.) Will the archer have to "duck"? Explain.

A movie stunt driver on a motorcycle can fly over a wide ditch with certain angle and initial speed. However, if he speeds horizontally, will he crosses this ditch? Consider his motion as projectile, and the two sides of ditch have equal altitude. Yes, he will if his initial velocity is big enough No, theoretically he will never cross this ditch It depends on the weather condition It depends on how powerful of his motorcycle Is it 1,2,3, or 4

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 211 m with a constant velocity of 47.0m / 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?

An outfielder throws a baseball to home plate and hits it ; it leaves his hand at a  velocity of +15 m/s and an angle of 40° . How  long does it take for the ball to hit the Home plate ( ground)? How far will the golf ball have traveled when it hits the Home Plate (ground)? How high will it go at  its highest point on way to home plate?   Notice you have 3 UNKNOWNS! Write a concluding sentence that states the whole result. I do not know the formula or how to solve this equation.
