A rocket booster fires in space with a force of 500N and moves the 10kg satellite from rest to motion in 2.1 seconds. Find the acceleration? What is the final speed of the satellite?

F= 500N , m= 10kg , t= 2.1s , a=? , v(f)=?
F= (m)(a) therefore a= F/m
so a= 500/10= 50ms
and v= u(i) + (a)(t)
so v(f)= 0 + (50)(2.1)= 105ms
note=== v(f) is final velocity and v(i) is initial velocity.
