Question

correct ans with solution ?​

Answer 1

Explanation:

just normal kinematics question but loaded with extra stuff.

they given

1.velocity at t=0

v=57.2m/s

2.mass and force by which we can find acceleration

F=ma

6.94×10^9=5.82×10^6×a

a=1.19 ×10^3m/s^2

v=u+at

given u=0

t=25.4s

v=0+1.19×10^3×25.4

v=30.226×10^3m/s
