Thomas throws a tennis ball vertically upward. The ball returns to the point of release after 10 s. The initial speed of the ball as it thrown upward is approximately ___ m/s

From a height of 11.0 m an object is sent directly downward with an initial velocity of 1.2 m/s. Determine how long the object stays in the air before touching the ground below. 1.38 s 1.20 s 1.86 s ○ 1.00 s

How long does it take to hit the ground?

starting from rest, a rocket is launched upward (a=4.20 m/s^2). At t=6.85 sec, the motor shuts off the rocket continues to coast upward until it reached its highest point. At highest point, a chute was introduced so that the rocket will fall at a constant speed of 0.935 m/s until it reaches the ground. Determine the maximum height, h, in meters

While standing at the edge of the roof of a building, a man throws a stone upward with an initial speed of 6.61 m/s. The stone subsequently falls to the ground, which is 17.3 m below the point where the stone leaves his hand. At what speed does the stone impact the ground? Ignore air resistance and use ?=9.81 m/s2 for the acceleration due to gravity. A) Impact speed: _________________________ m/s     B) How much time is the stone in the air? elapsed time: ____________ s

A car traveling in a straight line with an initial velocity of 34 m/s accelerates at a rate of 2.0 m/s2 to a velocity of 58 m/s. What is the distance covered by the car in this process?

A cart is given an initial velocity of 13.5 m/s and experiences a constant acceleration of 2.5 m/s2. What is the magnitude of the cart's displacement during the first 11 s of its motion?

A ball is thrown straight up with an initial speed of 15.5 m/s. At what height above its initial position will the ball have one‑half its initial speed? height:   m

At time t=0 a stone is dropped from a bridge.  Δt=1.1 s later a second stone is thrown down.  Both stones hit the ground 40 meters below the bridge at the same time.  What was the initial velocity of the second stone? Use g = 10m/s/s and answer to the 0.1 m/s.

an object has a velocity of (5.4 m/s)i - (5.8 m/s)j. over a period of 1.3 s, its velocity changes to (1.7 m/s)i + (5.9 m/s)j. What is the displacement
