A car weighing 100kg is on a slope that makes and angle `30^(@)` with the horizontal. The component of car's weight parallel to the slope is `(g=10ms^(-2))`

A man pushes a 80 N crate a distance of 5.0 m upward along a frictionless slope that makes an angle of 30^@ with the horizontal. The force he exerts is parallel to the slope. If the speed of the crate increases at a rate of 1.5 then the work done by the man is :

A boy wants to hold a 50 kg box on a snow covered hill. The hill makes an angle of 30^(@) with the horizontal. What force the boy must exert parallel to the slope ?

A helicopter while flying at a height of 100 m with velocity 30 m.s at an angle 30^(@) with the horizontal, drops a packet. Where will the packet strike the ground ? ( g = 10 m//s^(2) )

A body of mass 10kg is placed on a smooth inclined plane making an angle of 30^(@) with the horizontal, the component of the force of gravity trying to move the body down the inclined plane is [g=9.8m//s^(2)]

A particle is thrown at time t = 0 with a velocity of 10 ms^(-1) at an angle 60^@ with the horizontal from a point on an inclined plane, making an angle of 30^@ with the horizontal. The time when the velocity of the projectile becomes parallel to the incline is

A ball is thrown with a velocity of 30 ms^(-1) from the top of a building 200m high . The ball makes an angle of 30^(@) with the horizontal . Calculate the distance from the foot of the building where the ball strikes the ground (g=10ms^(-2)) .
