A ball is projected from a point `A` with some velocity at an angle `30^@` with the horizontal as shown in (Fig. 5.204). Consider a target at point `B`. The ball will hit the target if it thrown with a velocity `v_0` equal to.

A ball is projected from a point in a horizontal plane with a velocity of 20 m/s at 30^(@) with the horizontal. Coefficient of restitution is 0.8, then

A ball is thrown from a point O aiming a target at angle 30^(@) with the horizontal so that the ball hits the target at B but the ball hits at point A, a vertical distance h below B. If the intial velocity of the ball is 20 ms^(-1) and the horizontal distance between O and C is 10 m. Find the value of h.

A ball is thrown from a point O aiming a target at angle 37^(@) with the horizontal so that the ball hits the target at C but the ball hits at point D , a vertical distance y_(0) below C . If the initial velocity of the ball is 10 m//s and the horizontal distance between O and C is 5 m . Find y_(0) .

A ball is projected horizontal from the top of a tower with a velocity v_(0) . It will be moving at an angle of 60^(@) with the horizontal after time.
