A horizontal force of 1.2 kgf is applied to a 1.5 kgf block, which rests on a horizontal surface. If the coefficient of friction is 0.3, find the acceleration produced. Given, `g=9.8ms^(-2)`.

m_1 and m_2 are the masses of two bodies. When a force of 5 N is applied on each body, m_1 gets an acceleration of 10 m//s^2 and m_2, 20 m//s^2. If the two bodies are tied together and the same force is applied, find the acceleration of the combined system.

A block of mass 15 kg is placed on a long trolley. The coefficient of friction between the block and the trolley is 0.18. The trolley accelerate from rest with 0.5 ms^-2 for 20 s and then moves with unifrom velocity. Discuss the motion of the block as viewd by an observer with the trolley.
