Question

a body mass 40kg was moving velocity of 20m/s and reaches to the velocity 50 m/s in 1 minutes, then find force​

Answer 1

Answer:

20N

Explanation:

Given

m=40kg

vi=20m/s

vf=50m/s

t=1min

t=60s

Solution

vf=vi+at

50=20+a(60)

a(60)=50-20

60a=30

a=30/60

a=1/2 m/s2

F=ma

F=40(1/2)

F=20N
