Calculate the horizontal range covered by a stone thrown with velocity of `30m//s` inclined at an angle of `45^@` with the horizontal Assume `g=9.8m//s^2`

A particle is projected from horizontal making an angle 60^@ with initial velocity 50m/s . The time taken by the particle to make an angle of 45^@ from the horizontal is

From the top a building 39.2 m high, a ball is thrown by a velocity of 19.6 m/s in the downwards direction making an angle of 30^@ with the horizontal. Find the time ball takes to hit the ground and the horizontal range. g= 9.8 m/ s^2

From the top of a cliff 73.5 m a body is projected with a velocity of 19.6 m/s at an angle of 30^@ with the horizontal. Determine the time of flight, the distance from the foot of the tower and velocity with which the body strike the ground. g =9.8 m/ s^2

A cricket ball is rolled on ice with a velocity of 5.6 m/s and comes to rest after travelling 8 m. Find the coefficient of friction Given g=9.8m//s^2 .

Two bodies are thrown with same velocity at angle alpha and (90-alpha) with the horizontal. What is the ratio of their ranges ?

A mass M kg is suspended by a weightless string. What is the horizontal force that is required to displace it until the string makes an angle of 45^@ with the initial direction ?

A stone is thrown horizontal from the top of a tower with a speed of 50m/s. Find the velocity and position at the end of 3s.
