Question

Calculate the kinetic energy of a .2 kg golf ball travelling 30 m/s.
A..98 J
B.3 J
C.90 J
D.882 J

Answer 1

Explanation:

the answer is 90J

by formula 1/2× m× v^2

Answer 2

Mass=2 kg
v=30 m/s
We know that
Kinetic energy=1/2mv^2
=1/2*2*(30)^2
=30*30
=900 J
But the options given are wrong.900J should be included there
