A mass of `2.9 kg` is suspended from a string of length `50 cm` and is at rest . Another body of mass `100 gm` which is moving horizontal with a velocity of `150 m//s` strikes it . After striking the two bodies combine together . Tension in the string , when it is at an angle of `60^(@)` with the velocity is : `g = 10 m//s^(2)`

A mass of 2.9 kg, is suspended from a string of length 50 cm, and is at rest. Another body of mass 100 gm moving horizontally with a velocity of 150 m/sec, strikes and sticks to it. What is the tension in the string when it makes an angle of 60º with the vertical

A body of mass 4 kg moving with velocity 12 m//s collides with another body of mass 6 kg at rest. If two bodies stick together after collision , then the loss of kinetic energy of system is

The length of a ballistic pendulum is 1 m and mass of its block is 1.9 kg . A bullet of mass 0.1 kg strikes the block in horizontal direction with a velocity 100 ms^(-1) and got embedded in the block. After collision the combined mass swings away from lowest point. The tension in the strings when it makes an angle 60^@ with vertical is (g=10 ms^(-2)) .

A body of mass 2kg moving with a velocity of 6 m//s strikes inelastically another body of same mass at rest. The amount of heat evolved during collision is

A body of mass 3 kg moving with a velocity of 4 m//s towards left collides head on with a body of mass 4 kg moving in opposite direction with a velocity of 3 m//s . After collision the two bodies stick together and move with a common velocity which is

A body of mass 5 kg moving with a velocity 10 m/s collides with another body of the mass 20 kg at, rest and comes to rest. The velocity of the second body due to collision is

A ball of mass 10 kg is moving with a velocity of 10 m / s . It strikes another ball of mass 5 kg which is moving in the same direction with a velocity of 4 m / s . If the collision is elastic, their velocities after the collision will be, respectively

A mass of 10 gm moving with a velocity of 100 cm / s strikes a pendulum bob of mass 10 gm . The two masses stick together. The maximum height reached by the system now is (g=10m//s^(2))

A body A of mass 5kg is moving along the x-axis with a velocity 2m/s. Another body (B) of mass 10 kg is moving along the y-axis with a velocity sqrt(3)m//s . They collide at the origin and stick together. What is the final velocity of the combined mass?
