I have three questions. Please explain step by step!!!!
1) A ball is tossed vertically upward from a height of 2m above the ground with an initial velocity of 10 m/s. As the ball hits the ground, what will be the ball’s speed?
2) A soccer player kicks a ball with a projection velocity of 10.25 m/s with a projection angle of 22 degrees. What is the range of the soccer ball?
3)A pole-vaulter takes 1.5 seconds to fall from a peak height to a landing mat. What is his vertical velocity at contact with the mat?

A soccer player kicks a ball with a velocity v0 = 9 m/s at an angle of 30°from the horizontal. (a) Draw a picture of this problem and determine (b) the time it takes the ball to fall back to the ground, (c) the distance to the point where the ball hits the ground, and (d) the maximum height reached by the ball.

A soccer ball is kicked from the ground with an initial speed of 17.6m/s at an upward angle of 42.5 degrees. A player 49.4 m away in the direction of the kicks starts running to meet the ball at that instant. What must be his average speed if he is to meet the ball just before it hits the ground? Neglect air resistance.

A ball A is thrown vertically upward from the top of a 33-m-high building with an initial velocity of 3 m/s. At the same instant another ball B is thrown upward from the ground with an initial velocity of 23 m/s. Determine the height from the ground at which they pass. Determine the time at which they pass.
A ball falls from height of 19.5 m, hits the floor, and rebounds vertically upward to height of 15.0 m
A ball falls from height of 19.5 m, hits the floor, and rebounds vertically upward to height of 15.0 m. Assume that mall 0.390 kg. (a) What is the impulse (in kg. m/s) delivered to the ball by the floor? (b) If the ball is in contact with the floor for 0.0400 seconds, what is the average force (in N) the floor exerts on the ball?

A 55-kg soccer player jumps vertically upwards and heads the 0.45-kg ball as it is descending vertically with a speed of 23 m/s. (a) If the player was moving upward with a speed of 4.0 m/s just before impact, what will be the speed of the ball immediately after the collision if the ball rebounds vertically upwards and the collision is elastic?(b) If the ball is in contact with the player's head for 23 ms, what is the average acceleration...
A ball is thrown vertically upward with an initial velocity of 96 feet per second
A ball is thrown vertically upward with an initial velocity of 96 feet per second. The distance s (in feet) of the ball from the ground after t seconds is s(t)=96t-16t^2a.) at what time will the ball strike the groundb.) for what time t is the ball more than 128 feet above the ground?c.) when will the ball reach its highest peak? how high is it above the ground?
A ball A is thrown vertically upward from the top of a 33-m-high building with an initial velocity of 3 m/s.
