1. 500 kg roller starts from a point A as shown in the diagram below. If throughout its travel the average retarding force due to air friction on the wheel is 200 N. What is its speed at points B and C given that |AB| = 100 m and |BC| = 50 m. How far will it travel at the 1 elevation of C before coming to rest? A 20 m 5 m B 2. Under a constant force, a 10 kg ball increases its speed from 2.0 ms to 7 ms after covering 50 m. Calculate the force on the ball.
