(a)An object is thrown up a smooth plane inclined at an angle of 30° to the horizontal. If the plane is 15 m long and the object comes to rest at the top, find the
(b)Forces of magnitudes 5N, S..J3N. 10 N, S...[3N and 5 N act on a body P, ohnass 5 kg as
s'hown in the diagram.
Find tLl~ (i)
(Y~)
5N magnitude of the resultant force;
acceleration of the body.
