![1. Which component of the gravitational force affects each of the following for an object
sliding down a ramp?
a. acceleration down the incline
b. the force of friction
C. the tension in a rope pulling the object up the ramp
2. You are holding an 85 kg trunk at the top of a ramp that slopes from a van to the ground,
making an angle of 35° with the ground. You lose your grip and the trunk begins to slide.
a. Draw a FBD of the situation.
b. Resolve F into its component vectors. Include values in the diagram.
g
c.
If the coefficient of friction between the trunk and the ramp is 0.42, what is the
acceleration of the trunk?
d. If the trunk slides 1.3 m before reaching the bottom of the ramp, for what time
interval did it slide?
3. A boy is pulling a sled and rider with a combined mass of 82 kg up a 6.5° slope at a
steady speed. The coefficient of kinetic friction between the sled and snow is 0.10.
Draw a FBD of the situation.
a.
b. Resolve F, into its component vectors. Include values in the diagram.
c. What is the tension in the rope?
6. A boy pushes a lawn mower (m = 17.9 kg) starting from rest across a horizontal
lawn by applying a force of 32.9 N straight along the handle, which is inclined
at an angle of 35.1° above the horizontal. The magnitude of the mower's accel-
eration is 1.37 m/s2, which lasts for 0.58 s, after which the mower moves at a
constant velocity. Determine the magnitude of
(a) the normal force on the mower
(b) the frictional force on the mower
(c) the maximum velocity of the mower
(d) the force applied by the boy needed to maintain the constant velocity](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5bf302ec-1eb7-473e-a7d2-a2c00bc5169d%2Ff62ce09e-ef34-4dba-a9be-d5a203a7fbc7%2Fvwc132p_processed.jpeg&w=3840&q=75)
