Question

A starting A resultant force of 25 Newton's act on a mass of 0.50kg starting from rest find acceleration in m/s2,final velocity after 20 minutes, distance moved in 20 minutes

​

Answer 1

Using Newton's second law of motion;

F=ma

25=0.25a

a=25/0.25=100 m/s²

After 20 minutes;

Vf=at+Vi

Vf=100(1200)+0

Vf=120000 m/s

d=at²/2 +Vi×t

d=100(1200)²+0

d=144 000 000 meters
