Ball `I` is thrown towards a tower at an angle of `60^@` with the horizontal with unknown speed `(u)`. At the same moment, ball `II` is released from the top of tower as shown in (Fig. 5.189). Balls collide after `2 s` and at the moment of collision, the velocity of ball `I` is horizontal. Find the
(a) speed `u`
(b) distance of point of projection of ball `I` from base of tower `(x)`
( c) height of tower
.

A ball is projected at an angle 60^(@) with the horizontal with speed 30 m/s. What will be the speed of the ball when it makes an angle 45^(@) with the horizontal ?

A ball is thrown horizontally and at the same time another ball is dropped down from the top of a tower Will both the balls reach the ground at the same time ?

A ball is thrown horizontally and at the same time another ball is dropped down from the top of a tower Will both strike the ground with the same velocity ?

A ball is thrown with velocity 40 m//s at angle 30^(@) with horizontal from the top of a tower of height 60 m . At what horizontal distance from the foot of tower, the ball will strike the gorund ?

A ball is thrown with speed 40 m//s at an angle 30^(@) with horizontally from the top of a tower of height 60 m . Choose the correct option

A ball is projected form top of a tower with a velocity of 5m//s at an angle of 53^(@) to horizontal. Its speed when it is at a height of 0.45m from the point of projection is:

A ball of mass m is thrown at an angle of 45^(@) to the horizontal,, from the top of a 65 m high tower AB as shown in Fig. at t = 0 . Another identical ball is thrown with velocity 20 m//s horizontally towards AB from the top of a 30 m high tower CD 1 s after the projection of the first ball. Both the balls move the same vertical plane. If they collide in mid-air, the height from the ground where the two balls will collide is
