Two balls are thrown simultaneously in air. The acceleration of the centre of mass of the two balls while in air

A

depends on the direction of the motion of the balls.

B

depends on the masses of the two balls.

C

depends on the speeds of two balls

D

is equal to g

Text Solution

Verified by Experts

The correct Answer is:
D
Both the balls in airhve acceleration g downwards. Hence the acceleration of their center of mass will also be g downwards.

Two balls of same mass are released simultaneously from heights h & 2h from the ground level. The balls collide with the floor & stick to it. Then the velocity-time graph of centre of mass of the two balls is best represented by :

Assertion: Two bodies of masses M and m(M gt m) are allowed to fall from the same height if the air resistance for each be the same then both the bodies will reach the earth simultaneously. Reason: For same air resistance, acceleration of both the bodies will be same.

Two balls are thrown simultaneously from ground with same velocity of 10 ms^(-1) but different angles of projection with horizontally. Both balls fall at same distance 5sqrt(3)m from point of projection. What is the time interval between balls striking the ground ?

A ball of mass M and radius R is released on a rough inclined plane of inclination theta . Friction is not sufficient to prevent slipping. The coefficient friction between the ball and the plane is mu . Find (a). The linear acceleration of the ball down the plane. (b). the angular acceleration of the ball about its centre of mass.

A ball is thrown straight up. What is its velocity and acceleration at the top?

In the figure shown, the two identical balls of mass M and radius R each, are placed in contact with each other on the frictionless horizontal surface. The third ball of mass M and radius R//2 , is coming down vertically and has a velocity = v_(0) when it simultaneously hits the two balls and itself comes to rest. Then, each of the two bigger balls will move after collision with a speed equal to
