For a short period of time, the frictional driving force acting on the wheels of the 2.5-Mg van is Fp = 600t> N, where t is in seconds. If the van has a speed of 20 km/h when t = 0 s, determine its speed whent=35s. The 40-kg slider block is moving to the right with a speed of 1.5 m/s when it is acted upon by the forces F; and F,. If these loadings vary in the manner shown on the graph, determine the speed of the block at t = 6 5. Neglect friction and the mass of the pulleys and cords. F(N) The winch delivers a horizontal towing force F to its cable at A which varies as shown in the graph. Determine the speed of the 70-kg bucket when t = 18 s. F Originally the bucket is moving upward at v1 = 3 m/s. F(N) 600 360 B 12 24 1 (s)The 50 kg boy jumps on the 5 kg skateboard with a horizontal velocity of 5 m/s. Determine the distance s the boy reaches up the inclined plane before momentarily coming to rest. Neglect the skateboard's rolling resistance
