a small block B of mass M is quickly on an inclined plane P which makes an angle theta with the horizontal cart C, on which P is rigidly fixed
the coefficient of friction between the block B and the plane C is mu.
when the card statys stationary the block slides down if the car is moving in the horizontal direction with acceleration a the minimum value of a for which the block remain static is

Answer: the only force bringing the block down=f mg sin∅
a) f=mg sin∅
ma=mg sin∅
a=g sin∅=acceleration
b) force exerted by incline is the normal reaction force
N= mg cos∅
