Question

If force=100N, mass=20kg, final velocity=50m/s, initial velocity=20m/s find timewhy​

Answer 1

Explanation:

we have to first find acceleration

F=ma

100=20×a

50 = a

hence acceleration is 50m/s

from first equation of motion

v=u+at

50=20+50t

50-20=50t

30=50t

30/50=t

hence time taken 0.6 seconds
