A car of 1000 kg, is accelerating due to a net force 1200 N. If 4 people of mass 50 Kg board the car, then what is the new acceleration ? (in M/s2)
Total mass = 1000 + (4*50) = 1200 Kg
Force = 1200 N
Acceleration = Force / Mass = 1 m/s2
An object has a initial velocity of 10 m/s and acceleration of 2 m/s2, then what is the net force applied by the engine to the car of mass 50 Kg?
Suppose that a box is accelerating at a rate of 2 ms2. If the net force is tripled and the mass is doubled, then what is the new acceleration of the box? (in ms2)
Two boys push a car of mass 1000 kg at a uniform velocity along a level road. The same car can be pushed by three boys to produce an acceleration of 0.5 ms−2.. With what force does the person push the car? ( The effort with which the boys pushed the car was the same)
