Question

A worker who is 1.5 m above the ground places a 50 kg crate on a curved, frictionless ramp. After sliding down the ramp, the crate slides for 5 m across a rough section of floor whose coefficients of kinetic and static friction between the crate and ramp are 0.17 and 0.20, respectively. After this, the crate strikes a bumper that acts as an ideal spring with spring constant 1500 N/m.

a) What is the speed of the crate just before it hits the spring?

b) What is the maximum compression of the spring?

c) On returning, does the crate reach the curved ramp?

Answer #1

A worker wants to load a 12 kg crate into a truck by sliding the
crate up a straight ramp which is 2.5 m long and which makes an
angle of 30 degrees with the horizontal. The worker believes that
he can get the crate to the very top of the ramp by launching it at
5 m/s at the bottom. Note that the worker does not keep pushing on
the crate. But the worker underestimated or even forgot about...

A 55-kg crate is pulled horizontally 7.0 m across the floor by a
force F whose magnitude is 160 N. The force F is parallel to the
displacement of the box. The coefficient of kinetic friction is
0.25.
A. If the crate starts from rest, use the work-energy theorem to
find the velocity of the crate after it has moved 7.0 m
horizontally.
B. After the crate has moved 7.0 m horizontally, the external
force F no longer acts on...

A.Your mass m=11 kg block slides down a frictionless ramp having
angle theta=0.51 radians to the horizontal. After sliding down the
ramp a distance L=16 m the block encounters a spring of spring
constant k=551 N/m. The spring is parallel to the ramp. Use g=9.74
m/s/s for the acceleration of gravity.
Calculate the maximum compression of the spring, in meters.
Include labeled diagrams showing the initial and final
configurations, and a discussion of the solution method based on
energy conservation....

3-A 1.0 kg block slides down an inclined plane of 39
0 from the horizontal. If the
block starts from rest and hits the bottom in 5.1 s,
what is the speed of the block, in the unit m/s, at the bottom of
the incline? Assume a frictionless plane.
4-A bus negotiates a turn of radius 103 m while traveling at a
speed of 92 km/h. If slipping just begins at this speed, what is
the coefficient of static friction between the...

Two boxes are stacked, with box B placed on top of box A. If box
A is pushed such that both boxes move with a decreasing speed, is
there any friction on either box?
(a) Kinetic friction on box A and no friction on box B (b)
Kinetic friction on box A and static friction on box B
(c) Kinetic friction on box A and kinetic friction on box B (d)
Static friction on box A and kinetic friction on...

between A and B?
A) 625 J
B) 20.0 J
C) 275 J
D) 75 J
E) 0 J
