Question

What is the kinetic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s? (Formula:)

a) 25 J
b) 5 J
c) 50 J
d) 100 J

Answer 1

a) 25 J

Step-by-step explanation:

Formula for kinetic energy= 1/2(mv^2)

where m(mass) =0.5kg

v(velocity) =10m/s

Therefore, Kinetic energy= 1/2(0.5*10*10)

KE =1/2(50)

KE =25 J
