Question

4. What is the kinetic energy of a 4 kg volleyball that travels a distance of 40 meters in 2 seconds​

Answer 1

Explanation:

velocity =distance/time

v=40/2=20

mass =4kg

K.E =1/2mv^2=1/2*4*20^2=800

Answer 2

Answer:

KE=1/2×m×v²

here velocity=total distance/total time

v=40/2

 =20 m/s

m=4 kg

KE = 1/2×4×20×20

    =1/2×4×400

    =800 N/m
