A motor cyclist is trying to jump across a path as shown by driving horizontally off a cliff A at a speed of `5ms^(-1)`. Ignore air resistance and take `g=10ms^(-2)`. The speed with which he touches the peak B is:

A hiker stands on the edge of a cliff 490 m above the ground and throwns a stone horiozontally with an initial speed of 15ms^(-1) neglecting air resistance.The speed with which it hits the ground in ms^(-1) is (g=9.8ms^(2))

A hiker stands on the edge of a cliff 490 m above the ground and throws a stone horizontally with an initial speed of 15ms^(-1) Neglecting air resistance, find the time taken by the stone to reach the ground and the speed with which it hits the ground? (g=9.8ms^(-2))

A projectile is thrown horizontally with a speed of 20ms^(-1) .If g is (10ms^(-2)) ,then the speed of the projectile after 5 second will be nearly

How much work should be done on a bicycle of mass 20 kg to increase its speed from 2 ms^(-1) to 5ms^(-1) ? (Ignore air resistance and friction).

A body is projected vertically up with a speed of 20ms^(-1) .The distance travelled by it in "3" seconds it (g=10ms^(-2))

A body is projected at an angle of 30^(@) with the horizontal and with a speed of 30ms^(-1) . What is the angle with the horizontal after 1.5 second? (g=10ms^(-2))
