Question

E
m 5kg
F = 10 Newton
u = 3m\s

v= ?
it = 6 seconds​

Answer 1

Answer:

Force, F=10N

Mass, m=5Kg

Force,

F=ma

a=2m/s

2

Work done, W=F.ds

In first second, displacement,

s=

s=

1

×2×1

s=1m

So, work done,W=10×1=10J

In second second, s=

2

1

×2×4=4m

So, the displacement is , 4−1=3m

Hence, work done in 2 second is,

W=10×3

W=30J

Answer 2

Answer:

w=30J.................
