Question

2. A boy kicks the football of mass 500 g which is initially at rest. It starts moving with a
constant velocity of 5 m/s?. Calculate:
(a) the kinetic energy of the boy


​

Answer 1

Answer:

grams convert into kg

Explanation:

mass * acceleration

m* U- v/ t

0.5*10/5o

500 * 0.5

250

Answer 2

Answer:

(a)KE=6250

Explanation:

WE NEED TO FIND THE KINETIC ENERGY OF THE BOY.

K.E=1/2mv2

by substituting the given values

K.E=12500/2

=6250.
