From this paper
A person walks first at a constant speed of 5.00m/s along a straight line from point A to point B and then moves back along the line from B to A at a constant speed of 3.00m/s. What is: a) Her average speed over the entire trip? (5mks) b) Her average velocity over the entire trip? (5mks)
A 3.00kg block starts from rest at the top of a 30.0 ◦ incline and slides a distance of 2.00m down the incline in 1.50s. Find: a) The magnitude a of the acceleration of the block. (5mks) b) The coefficient of kinetic friction μk between the block and the plane. (5mks) c) The friction force ⃗ fk acting on the block. (5mks) d) The speed v2 of the block after it has slid 2.00m. (5mks)
