Question

An 8.00 kg block of ice starts at rest and slides down a 1.50 m long frictionless ramp angled at 35° from the horizontal.
a.) Draw a free body diagram for the block of ice.
b.) What is the acceleration of the block down the ramp?
c.) How long does it take the block to reach the bottom?
d.) What is the speed of the block at the bottom of the ramp?
e.) If the ramp had a coefficient of kinetic friction of 0.20, what is the frictional force on the block of ice?
f.) What would be the acceleration under this new condition of friction, assuming the angle of the ramp is the same?

Answer 1

the acceleration =\[gsin \theta\]
=(9.81)sin35
this is the angular component of the acceleration due to gravity=(9.81)
therefore my answer is =5.63 m/s
