Question

Force-5N
Velocity- 5m/s to 7m/s
Mass- 2kg
Time- ??​

Answer 1

Answer:

Force=ma

5N=2kg×a

a =5/2 m/s^2

But

a=(v-u)/t

=(7-5)/t

=2/t

Hence,

2/t=5/2

t/2=2/5

t=(2/5)×2

=4/5 s

=0.8s

Hope it helps you my dear friend.

Please mark me brainliest.

Have a great day.

Answer 2

Answer:

Mass =2kg Velocity 2*(5-7/5)=50
