QHQBP A(n) 11 kg mass is on an incline, with a = 4.7_m and b = 2.3_m. The coefficient of kinetic friction between the mass and the surface of the incline is k = 0.38. If the mass is initially near the top of the incline and sliding down, then what is the mass's acceleration down the incline? m b 16. 0.9627_m/s² 1.041_m/s² 1.103 m/s² A. B. C. 1-1 a D. E. F. 1.137 m/s² 1.01 m/s² 1.073_m/s²

A crate starts from rest and slides 8.05 m down a ramp. When it reaches the bottom it is traveling at a speed of 5.55 m/s. If the ramp makes an angle of 23.0o with the horizontal, what is the coefficient of friction between the crate and the ramp?

Determine the force Q-> when the block moves with constant velocity. Express your answer in vector form.

The coefficient of static friction between a rubber tire and dry pavement is about 0.800. Assume that a car's engine only turns the two rear wheels and that the weight of the car is uniformly distributed over all four wheels. What limit does the coefficient of static friction place on the time fmin required for a car to accelerate from rest to 50.0 mph (22.4 m/s)? Imin = How can friction accelerate a car forward when friction opposes motion?

While loading furniture into a truck, you push a 1.56 kg chair up a 14.7 degree ramp, with a horizontal force of 12.1 N. How long does it take to reach a speed of 4 m/s, starting from rest? The coefficient of kinetic friction chair - ramp is 0.345.

A block with a mass of 3.00 kg starts from rest at the top of a 27.5° incline and slides 2.00 m down the incline in 1.60. What is the coefficient of kinetic friction between the block and the incline?

Time left 0:20:32 An amusement park in Dubai has a ramp which is frictionless. A child drops a smooth object and it slides down the ramp and comes down through a height 4 m. What distance is necessary to stop the object on the flat track if the coefficient of friction is 0.4? h. Answer:

Two crates of fruit  are released from the top of a ramp inclined at 30 degrees from the horizontal and 4.5 meter long. The two crates consist of  an apple crate of mass 20 kg that is placed in front of a watermelon crate of mass 80 kg.  The apple crate has a coefficient of friction of 0.20 while the watermelon crate has a coefficient of friction of 0.15. How long does it take the apple crate to reach the bottom of the incline if it needs to travel a distance of 4.5 meters?
