Question

please solve the following question

Answer 1

given that the time for which force x is equal to 10 seconds
the mass of the body is equal to 10.2 kilogram
initial velocity is equal to zero
since the force caesars to act on the body after 10 second then the rest of the distance is covered with uniform velocity so the final velocity is equal to 0.5/5=0.1m/s

since the force is equal to product of mass and acceleration
=10.2×(10.2×0.1-0)/10
=10.2×1.02/10
=1.04N
