TEC 114: Basic Mechanics

1. A body of mass 16kg is pulled along a smooth horizontal table by a constant force. It describes 18m from rest in 3 seconds. Find the magnitude of this force

2. A body of mass 25kg is acted upon by a constant force for which in 10 seconds gives it a velocity of 75m/s. What is the magnitude of this force?

3. A block of mass 3kg is moving along a horizontal smooth surface with a velocity of V at time t=0. A force of 32.7N is applied against the direction of motion. The force shows to half the original velocity while it notes through 9m

i. What is the initial velocity

ii. How long does it take to occur

4. An engine exerts a uniform force of 19620 N on a train 100tons where its resistance is 62N per ton. Find the time required to get up a velocity of 30m.p.h from rest

5. An engine of mass 120 tons is coupled to and pulls a carriage of 80 tons. The resistance to the motion of the engine is 1/80 of its weight and that of the carriage is 1/100 of its weight. Find the tension in the coupling (union) if the whole tractive force exerted by the engine be equal to the weight of 12,152lbs (1kg=2.205lb)

6. A body moves up a smooth inclined plane starting with a velocity of 48ft/s. If the plane is inclined at 30 degrees, find the velocity of the body when it has moved 64ft from the starting
