A ball thrown by one player reaches the other in 2 seconds. The maximum height attained by the ball above the point of the projection will be

A particle is moving eastwards with a velocity of 5 m/s. In 10 sec the velocity changes to 5 m/sec northwards. The average acceleration in this time is

A projectile can have the same range R for two angles of projection. If T₁ and T₂ be the time of flights, then the products T₁T₂ is directly proportional to

A cricket ball of mass 250 g collides with a bat with velocity 10 m/s and returns with the same speed within 0.01 s. the force acted on the bat is.

Two bodies of mass 3 kg and 4kg are suspended at the ends of mass less string passing over a frictionless pulley. The acceleration of the system is (take g= 9.8 m/s²)
