The Newton’s second law of motion, can be expressed as – Force ∝ change in momentum/time taken or, F ∝ mv-mu/t or, F ∝ m(v-u)/t or, F ∝ ma or, F = kma [where k is constant] But the value ...

Given, mass m = 2 kg, velocity v = 4 ms⁻¹. As the object is moving with a constant velocity i.e., 4 ms⁻¹. So, the acceleration of the object is zero i.e., a = 0 and according to the property ...
