Two adjacent blocks of mass m1 = 3.0 kg and m2 = 4.0 kg are on a frictionless surface.A force of 6.0 N is applied to m1,and a force of 4.0 N is applied to m2 ;these antiparallel forces squeeze the blocks together.What is the force due to m1 on m2? Due to m2 on m1? What is the acceleration of the system?

A child of mass 20 kg slides down a 6.0 m long
slide, which makes an angle of 30° with the
horizontal. The coefficient of kinetic friction
between the child and the slide is 01. If the
child is at rest at the top of the slide, what is
her speed at the bottom ? How much energy is
transferred to thermal energy ?
Take g = 10 ms 2.

A crate of mass 75 kg is pulled along a
horizontal floor with constant velocity
by a rope attached to the crate. The
coefficient of kinetic friction between
the floor and the crate is 0.2 and the
angle the rope makes with the
horizontal is 45°. Calculate the
magnitude of the force exerted on the
crate by the rope. Draw the free body
diagram. Take g = 10 ms 2.
