Question

The force of 10000 newton is applied on the body for 10 sec such that the initial velocity is 30 metre per second. displacement is 2 km. find mass of body, final velocity, acceleration and work done.
plz tell me answer quickly​

Answer 1

Explanation:

F = 10000 N

T = 10s

U = 30m/s

S = 2000m

S= ut + 0.5at²

2000 = 30(10) + 0.5a(10)²

a=34m/s²

F=ma

10000=m(34)

m=5000/17 kg

V=u+at

V=30+34(10)

V=370m/s

W=FS

W=10000x2000

W=2x10^7 J
