let the mass = m θ1 = 30oθ2 = 60o The frictional force on an inclined surface is given by : frictional force = μ×m×g×Cosθfor 30o inclined surface , frictional force = μ×m×g×Cos(30o) = 0.866×μ×m×gfor 60o inclined surface , frictional force = μ×m×g×Cos(60o) = 0.5×μ×m×gHence, frictional force is greater for the block A released from 30 degree inclinedsurface and hence the speed of block B will be faster as the bottom of the inclined surface as the loss of energy due to friction is greater for block A Therefore, option D is correct

Two blocks with the same mass are released from the top of two inclined planes of the same height. Block A is released from an incline making 30-degree angles with the horizontal, while Block B is released from an incline making a 60-degree angle with the horizontal. The coefficient of friction is the same for both. Which of the blocks is going faster when it reaches the bottom of its respective incline? Од О We must know the actual masses of the blocks to answer. Block A is faster. Both blocks have the same speed at the bottom. Block B is faster. There is not enough information to answer the question because we do not know the value of the coefficient of kinetic friction.
