Question

Which Required more force on a body of mass 2 kg moving with an acceleration 5 metre per second another body of mass 2 kg moving with an acceleration of 4 metre per second

Answer 1

force = mass × acceleration .
in the first case force = 2 × 5 = 10Newton
in the second case force = 2 × 4 = 8Newton
therefore first force > second force.
