A baseball is hit almost straight up into the air with a speed of 27 m / s . A.) Estimate how high it goes. Express your answer to three significant figures and include the appropriate units.
0.5m v^2 = mgh. 0.5 *16*16 = 9.8* h. so h = 1.33 m . SECOND PART. as the motion is kinetic motion in one dimensional. so, time to go maximum height , t1. as, v= u+at here a= -g because acceleration is acceleration due to gravity which always act downward. v=0 at maximum height. so t1 = u/g = 16/9.8 = 1.63 s .
A baseball is hit nearly straight up into the air with a speed of 24 m / s . A) How high does it go? B) How long is it in the air ?, Solutions for Chapter 2 Problem 42P: (II) A baseball is hit almost straight up into the air with a speed of 25 m / s . Estimate (a) how high it goes, (b) how long it is in the air . Estimate (a) how high it goes, (b) how long it is in the air .

10/30/2018 · nap14hockey. So, this is a problem where the accleration is not provided, since it is implied. The only acceleration is acceleration due to gravity (9.8 m / s ) The equation we will use for this problem is. V is the final velocity, V? is the initial velocity, a is the acceleration, X is.
A baseball is hit straight up into the air. The ball spends exactly 7.0 s in total flight time in the air. Remember that the acceleration due to gravity is a constant 9.81 m/s. 2. Hint: Turn this into two separate motions: One upwards and one downwards. Be careful with your sign for acceleration.
