A car 2 m long and 3 m wide is moving at 13m/sec when a bullet hits it in a direction making an angle `theta=tan^(-1) 3//4` with the car as seen from the street. The bullet enters one edge of the comer and passes out at the diagonally opposite comer. Neglectingany interaction between bullet and car find the time for the bullet to cross the car :

A car 2m long and 3m wide is moving at 10m//s when a bullet hits it in a direction making an angle of tan^(-1)(3//4) with the car as seen from the ground. The bullet enters one edge of the car at the corner and passes out at diagonally opposite corner. Neglecting gravity, the time for the bullet to cross the car is

A bullet of mass m moving at a speed v hits a ball of mass M kept at rest. A small part having mass m ′ breaks from the ball and sticks to the bullet. The remaining ball is found to move at a speed v 1 ​ , in the direction of the bullet. Find the velocity of the bullet after the collision.

A block of wood of mass 3M is suspended by a string of length (10)/(3) m . A bullet of mass M hits it with a certain velocity and gets embedded in it. The block and the bullet swing to one side till the string makes 120^@ with the initial position. the velocity of the bullet is (g=10 ms^(-2)) .

A boy in the elevator shoots a bullet in a vertical upward direction from a height of 1.5 m above the floor of the elevator. There is no roof in the elevator. The floor of the elevator is at 50 m from ground at the instant when velocity of the elevator is 10 m/s in upward direction. The bullet strikes the floor of the elevator in 2 seconds. The initial speed of the bullet is 15 m/s relative to the elevator. Q. Find the displacement of the bullet relative to ground during its flight:
