find the force required to give a mass of 70kg an acceleration of 4m/sec2 horizontally and vertically.
Asked by Deepak Kumar Gupta | 29th Jul, 2012, 10:52: AM
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 =
