A body is thrown with a velocity of 9.8 m//s making an angle of 30^(@) with the horizontal. It will hit the ground after a time

If a body is thrown with a speed of 19.6m//s making an angle of 30^(@) with the horizontal,then the time of flight is

A ball is thrown upwards at an angle of 60^(@) to the horizontal. It falls on the ground at a distance of 90 m . If the ball is thrown with the same initial velocity at an angle 30^(@) , it will fall on the ground at a distance of

A ball is thrown at a speed of 40 m/s at an angle of 60^0 with the horizontal. Find a. the maximum height reached and b. the range of te ball. Take g=10 m/s^2 .

A ball is thrown upwards with a velcoity of 80 m//s at an angle of 30^@ to the horizontal . Find its velcituy after one second.

A boy throws a ball with a velocity u at an angle theta with the horizontal. At the same instant he starts running with uniform velocity to catch the ball before it hits the ground. To achieve this he should run with a velocity of

A ball was thrown by a boy a at angle 60^(@) with horizontal at height 1 m from ground. Boy B is running in the plane of motion of ball and catches the ball at height 1 m from ground. He finds the ball falling vertically. If the boy is running at a speed 20 km/hr. Then the velocity of projection of ball is-
