A block of mass 2.0 kg is placed on a smooth plane, inclined to the horizontal at an angle of 15°. The force of gravity, acting straight down on the block, is 20N.
a) What is the acceleration of the block down the plane?
b) How far up the plane was the block released, if it took 1.5 s to reach the bottom after it was released from rest?

A block is released from rest on an inclined plane and moves 2.9m during the nest 4.8 s. The acceleration due to gravity in9.8m/s^2. what is the magnitude of the block.

Additional information the block is 5kg. And the incline is 20degrees.

An object of mass 10 kg is placed on a plane inclined at an angle of 30 degrees

to the horizontal. The coefficient of kinetic friction between the object and the

plane is 0.12. The object is initially moving down the plane with a velocity of

4 metres per second. Calculate

(a) The acceleration of the block down the plane 

(b) The distance the object moves down the plane in the first five seconds.

A 10kg block is projected up a long 25 degrees incline with an initial velocity of 30ms. the coefficient of friction between the block and the incline is 0.25. a) Find the friction force acting on the block. b) Find the acceleration of the block up the plane. c) How long does it take the block to move up the plane? d) how far does the block move up the plane? e) what is the acceleration of the block as it moves down the plane?
