Question

a baseball has a mass of about 245 g suppose the player hits the ball across the table with a speed of about 4.00m/s,What's the ball's Kinetic Energy​

Answer 1

Answer:

1.96

Explanation:

K.E=1/2mv²

K.E=1/2*0.245kg*4*4=1.96

Answer 2

Given : a baseball has a mass of about 245 g

the player hits the ball across the table with a speed of about 4.00m/s,

To Find :  the ball's Kinetic Energy​

Solution:

KE = (1/2) m v²

KE = Kinetic Energy

m = mass

V = velocity

m = 245 g = 0.245 kg

v  = 4  m/s

KE = (1/2) * 0.245 * 4²

=> KE = 0.245 * 8

=> KE = 1.96  Joule

the ball's Kinetic Energy​ is  1.96  Joule
