find the force required to give a mass of 70kg an acceleration of 4m/sec2 horizontally and vertically.
Asked by Deepak Kumar Gupta | 29 Jul, 2012, 10:52: AM
answered-by-expert Expert Answer
let vertical direction be y and horizontal direction be x.
thus acceleration a = (4i + 4j) m/s2
mass, m = 70 kg
thus force = F = ma = 280(i+j) m/s2
it will make ann angle of 45 degree with each axis (as it has equal component in each direction )
and magnitude =

Two blocks of mass m=5kg and M=10 kg are connected by a string passing over a pulley B as shown. Another string connects the centre of the pulley B to the floor and passes over another pulley A as shown. An upward force F is applied at the centre of pulley A. Both the pulleys are massless. Find the acceleration of both the blocks if 1) F=100N.  2)F=500N

In the arrangement shown in the figure, a heavy pulley of mass M is suspended from a spring of stiffness constant K and the mass m is suspended from a string tightly wound on the pulley. If the mass m is given a small downward displacement and released, find the time period of small oscillations (Take pulley as Disc) and string does not slips on the pulley.
