Question

- A body travels a distance of 24 meters in 3 X 102 seconds. Assuming its speed was
constant, find its kinetic energy. (Take 1.5 X 10-20 kg as the mass of the body).
A. 40 X 10-16 joules
D. 48 X 10-16 joules
B. 41 X 10-16 joules
E. 55 X 10-16 joules
C. 36 X 10-16 joules​

Answer 1

Answer:

48x10*-16 joules

Explanation:

speed = distance/time

V=d/t =24/3x10*2

K=1/2mv*2

K= 1/2 x 1.5x10*-20 x (24/3x10*2)*2

=48x10*-16
