A stone is thrown at 25m//s " at " 53^(@) above the horizontal. At what time its velocity is at 45^(@) below the horizontal?

a ball is thrown with 25 m//s at an angle 53^(@) above the horizontal. Find its time to fight, maximum height and range.

a ball is thrown with 25 m//s at an angle 53^(@) above the horizontal. Find its time to fight, maximum height and range.

A body is projected with a velocity of 10 m//s at 45^(@) to the horizontal . The velocity of the projectile when it moves at 30^(@) to the horizontal is

A projectile is thrown with a velocity of 20 m//s, at an angle of 60^(@) with the horizontal. After how much time the velocity vector will make an angle of 45^(@) with the horizontal (in upward direction) is (take g= 10m//s^(2))-
