Here is a sample problem.
**003 (part 1 of 3) 10.0 points
A 4.02 kg block slides down a smooth, fric-
tionless plane having an inclination of 23◦ .
The acceleration of gravity is 9.8 m/s2 .
Find the acceleration of the block. Answer
in units of m/s2.
**004 (part 2 of 3) 10.0 points
What is the block’s speed when, starting from
rest, it has traveled a distance of 2.87 m along
the incline. Answer in units of m/s.
**005 (part 3 of 3) 10.0 points
What is the magnitude of the perpendicular
force that the block exerts on the surface of
the plane at a distance of 2.87 m down the
incline? Answer in units of N.
