Question: Q.1- A wooden block of mass 0.01 kg is dropped from the top of a cliff 100 high. simultaneously a bullet of man 0.01 kg is fired from the foot of the cliff vertically upwards with a velocity 100 m/s. If bullet after striking block gets embedded in it. How high will it rise above the cliff before it starts falling.
Q.2- A man of 2.9 kg is suspended from a string of length 50 cm and is at rest,another body of mass 100 kg. Which is moving horizontally with velocity of 150 m/s strikes and sticks to it.
i) What is the tension in the string when it makes an angle 60 degree with vertical.
ii) Will ti complete a vertical circle.
Q.3- A ball with a speed of 9 m/s strikes a stationary ball such that after collision in the direction of each ball makes angle 30 degree with the original direction of motion. What is the speed of the two ball after collision
