A ball is thrown at speed of 80 m/s in a direction 30° above the horizontal. The time taken by the ball to return to the same level is (Take, g = 10 m/s²)

A ball is thrown vertically upward with a speed of 40 m/s. The time taken by the ball to reach the maximum height would be approximately

The minimum power required to lift a mass of 50 kg up to a vertical distance of 8 m in 10 s is: (Take g = 10 m/s²)

A ball thrown up is caught by the thrower 6 sec after start. The height to which the ball has risen is (g = 10 m/s²):

When two bodies move uniformly towards each other, the distance decrease by 6 m/s. If both the bodies moves (as above) in the same direction with the same speed, the distance between them increases b…

A person is standing on a frictionless horizontal ground. How can he move by a certain distance on this ground?
