Homework help?? [ block on inclined plane ]
002 (part 1 of 3) 10.0 points
A 3.86 kg block slides down a smooth, fric-
tionless plane having an inclination of 28◦ .
The acceleration of gravity is 9.8 m/s2 .
Find the acceleration of the block.
Answer in units of m/s2.
003 (part 2 of 3) 10.0 points
What is the block’s speed when, starting from
rest, it has traveled a distance of 2.35 m along
the incline.
Answer in units of m/s.
004 (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 2.35 m down the
incline?
Answer in units of N.
