A metallic wire of 1 m length has a mass of 10×10−2 kg. If a tension of 100 N is applied to a wire, what is the speed of transverse wave?
A force of 100N is applied on a body of mass 2kg at rest for 3 seconds. What will be velocity of the body after 10 seconds of application of the force assuming no friction?
A block of mass 1 kg travelling in a straight line with a velocity of 10 ms−1 collides and sticks to a stationary wooden block of mass 5 kg. After this, they both move together in the same straight line. Calculate the total momentum just before the impact, just after the impact and the velocity of the combined object.
