5) A block of mass, m = 10.0 kg, is sliding along a frictionless
horizontal surface with an initial velocity of 8.00 m/s when it
encounters a frictionless ramp inclined at an angle of 0=30.0°
above the horizontal. Calculate the speed of the block when it
reaches a vertical height of 1.4 meters. [You may use g=10.0
m/s and choose the closest answer]
A) 3.0 m/s
B) 4.0 m/s
5.0 m/s
D) 6.0 m/s
E) 7.0 m/s
m
0
m = 10kg

A 4.25 kg block is projected at 5.40 m/s up a plane that is inclined at 30.0° with the horizontal. The block slides some distance up the incline, stops turns around and slides back down to the bottom. When it reaches the bottom of the incline again, it is traveling with a speed of 3.80 m/s. If the coefficient of kinetic friction between the block and the plane is 0.500, how far up the incline did the block slide?

5) An Amazon package (2 kg) starts from rest, then begins to slide down a 4 m tall ramp that is inclined at 30°. The package then travels 12 m along a horizontal surface where it pushes into a spring (k = 3000 N/m). The package compresses the spring a distance x before coming momentarily to rest. Then the package is pushed in the opposite direction by the spring. The coefficient of friction between the ramp/floor and the package is 0.21. Calculate x and determine if the package will stop before it gets back to the ramp or if it will begin to slide up the ramp.

As shown in the figure below, a 2.25 kg block is released from rest on a ramp of height h. When the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 15.0 cm that has a coefficient of kinetic friction ?k = 0.510. Find h (in m) such that the block's speed after crossing the rough patch is 3.60 m/s. (Enter a number.)?m
A girl on a skateboard (total mass of 33.6 kg) is moving at a speed of 12.0 m/s at the bottom of a long ramp. The ramp is inclined at 23° with respect to the horizontal. If she travels 14.1 m upward along the ramp before stopping, what is the net frictional force on her?

QI) ( A block of mass m-10 kg is on a frictionless horizontal surface and pushed against the spring, whose spring constant k-240 N/m, compressing the spring by 3m. The block is then released from rest. The block is observed to move up the incline and come back down, hitting and 771 compressing the spring by a maximum distance of Im. The inclined plane has www. friction and makes an angle of 9 = 37° with the horizontal. a) Find the work done by friction from the moment the block is released till the moment it strikes the spring again. b) What is the maximum height the block can reach? c) Find the kinetic friction coefficient between the block and the inclined plane.
