A projectile is fired horizontally with an initial speed of 20 m/s/ its horzontal speed 3 sec later is:

A projectile is fired horizontally from an inclined plane (of inclination 45^(@) with horizontal) with speed=50m/s. If g=10m//s^(2) , the range measured along the incline is

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

A projectile is fired at an angle of 30° to the horizontal with the speed v. If another projectile is projected with the same speed, then at what angle with the horizontal it must be projected so as to have the same range ?

A projectile is fired at an angle of 30° to the horizontal with the speed v. If another projectile is projected with the same speed, then at what angle with the horizontal it must be projected so as to have the same range ?

A 24-kg projectile is fired at an angle of 53^(@) above the horizontal with an initial speed of 50m//s . At the highest point in its trajectory, the projectile explodes into two fragments of equal mass, the first of which falls vertically with zero initial speed. (a) How far from the point of firing does the second fragment strike the ground? (Assume the ground is level.) (b) How much energy was released during the explosion?

A projectile is fired form the top of a 40 m high cliff with an initial speed of 50 m/s at an unknown angle. Find its speed when it hits the ground.

A projectile is fired form the top of a 40 m high cliff with an initial speed of 50 m/s at an unknown angle. Find its speed when it hits the ground.

A projectile is fired from the top of an 80 m high cliff with an initial speed of 30(m)//(s) at an unknown angle. The speed when its hits the ground.
