A kangaroo can jump 2.5 m vertically. What must be the initial velocity of the kangaroo?

A stone is thrown vertically upwards with initial velocity of 14 m s^-1 . The maximum height it will reach is [g= 9.8 m s^-2]

A stone is thrown vertically upwards with initial velocity of 14 m s^-1 . The maximum height it will reach is [g = 9.8 m s^-2]

A stone is thorwn vertically upwards with initial velocity of 40m//s . Taking g=10m//s^2 find the maximum height and total distance covered by stone

A projectile is thrown at an angle of 30^@ to the horizontal. What should be the range of initial velocity (u) so that its range will be betweeen 40m and 50m? Assume g= 10 m s^-2 .

A projectile is thrown at an angle of 30^@ to the horizontal. What should be the range of initial velocity (u) so that its range will be between 40m and 50 m? Assume g= 10 m s^(-2) .

Solve the following examples: (numerical problems) A body moves in a straight line with a uniform acceleration. If the initial velocity of the body is 5 m/s and the velocity after 10 s is 15 m/s, find the acceleration of the body and

The height y and the distance x along the horizontal, for a body projected in the vertical plane are given by y = 8t-5t^2 and x=6t , the initial velocity at t=0 of the body is

Solve the following examples: (numerical problems) A body moves in a Straight line with a uniform acceleration of 2 m/s^2 . If the initial velocity of the body is 10 m/s , find the velocity of the body after covering 75 m and the time taken by the body to attain this velocity.

A sphere of mass 'm' moving with velocity 'v' collides head-on on another sphere of same mass which is at rest. The ratio of final velocity of second sphere to the initial velocity of the first sphere is (e is coefficient of restitution and collision is inelastic)
