Question

A block of mass 0.5kg has an initial velocity of 10ms−1 down an inclined plane of angle 30°, the coefficient of friction between the block and the inclined surface is 0.2. What will be the velocity of the block after it travels a distance of 10m? a) 17ms−1 b) 13ms−1 c) 24ms−1 d) 8ms−1

Answer 1

this is your required answer

Explanation:

here f is friction and in first step I founder an equation using

net force = m a ( newton second law)
