A 40kg skatter moving at 4m/sec eastwards colloid head on with a 60kg scatter travelling at 3m/sec westward. if the two skatter remain in contact after collision. what is there final velocity.​

A 2 kg ball moving at 24 ms undergoes inelastic head on collision with a 4 kg ball moving in the opposite direction at 48 ms. If the coefficient of restitution is 2/3, their velocities in ms-after impact are

An object is dropped from a height of 120 m. The acceleration of the object is 10m/s downwards. Find the distance travelled by the object after 3s. What is the final velocity of the object after 3s?

An object is dropped from a height of 120 m. The acceleration of the object is 10m/s downwards. Find the distance travelled by the object after 1s. What is the final velocity of the object after 3s?

An object is dropped from a height of 120 m. The acceleration of the object is 10m/s downwards. Find the distance travelled by the object after 2s. What is the final velocity of the object after 3s?

A trolley of mass 200 kg moves with a uniform speed of 36 km//h on a frictionless track. A child of mass 20 kg runs on the trolley from one end to the other (10 m away) with a speed of 4 m s^-1 relative to the trolley in a direction opposite to the its motion, and jumps out of the trolley. What is the final speed of the trolley ? How much has the trolley moved from the time the child begins to run ?

A and B are two particles having the same mass m. A is moving along X-axis with a speed of 10ms^(-1) and B is at rest. After undergoing a perfectly elastic collision with B, particle A gets scattered through an angle of 30^(@). What is th edirection of motion of B, and the speeds of A and B, after the collision?

Two objects, each of mass 1.5 kg, are moving in the same straight line but in the opposite directions. The velocity of each object is 2.5 ms^(-1) before the collision during which they stick together. What will be the velocity of combined object after collision ?

The transvers displacement of a string (clamped at its both ends) is given by y(x,t) = 0.06 sin ((2pi)/(3)s) cos (120 pit) Where x and y are in m and t in s. The length of the string 1.5 m and its mass is 3.0 xx 10^(-2) kg. Interpret the wave as a superposition of two waves travelling in opposite directions. What is the wavelength, frequency, and speed of each wave ?
