Two blocks A and B of mass m1 and m2 respectively are kept in contact on a frictionless table.The experimenter pushes the block A from behind so that the blocks accelerate. If the block A exerts a force F on the block B,what is the force exerted by the experimenter on A. Incoming search terms:numericals on [...]
An 80 kg shell is flying at a speed of 36km/h. It explodes into two pieces and one piece of mass 20 kg stops. What is the velocity of other piece? (It’s a simple problem.

- “A source of sound frequency 256Hz is moving rapidly towards a wall with a velocity of 5m/s. How many beats per second will be heard if sound travels at a speed of 330m/s?”
A small smooth object slides down a smooth incline plane, inclined at am angle 30 to the horizontal. What is
- the acceleration down the plane?
- The time to reach the bottom if the plane is 50m long?
The object is now thrown up the plane with an initial velocity me 15m/s ; how long does it
