A force of 150 N pushes a 100 N block up an incline whose slope is 3 vertical to 4 horizontal. If the coefficient of kinetic friction is 0.12, determine the time required, in seconds, to increase the velocity of the block from 3 to 15 m/sec. The force is applied parallel to the incline.
A man in a flat bed truck starts from rest up a hill at an angle of 8 degrees. If he is carrying a 600 kg
crate in the back and the static coefficient of friction is 0.25, what is the maximum rate of
acceleration before the crate slides off of the back of the truck? How long will it take the truck to
600 kg

a. A vehicle with the handbrake drawn must be pushed and moved. The vehicle weight is 1200 kg, and the force required to push the vehicle is 300 kg (G=10 m/s2 can be taken). Determine the value of the coefficient of friction that occurs when the wheels of the car make a sliding movement on the asphalt. As the car is pushed and moved, the speed of the car increases to 3.6 km/h. Find the power spent on friction
b. An oil film was formed under the wheels while the same vehicle was pushed with the handbrake drawn, and the vehicle thrust was reduced to 6 kg (G=10 m/s2). Determine the value of the coefficient of friction that occurs between the molecules of the lubricant.
The speed of the vehicle increases to 3.6 km/h when the vehicle is moved by pushing on the oil film. Find the power spent on friction

- A light plane of mass 1200 kg makes an emergency landing on a short runway. With itsengine off, it lands on the runway at a speed of 35 m/s. A hook on the plane snags acable attached to a 130 kg sandbag and drags the sandbag along. Now you can consider thesystem as a combined mass along with the sandbag and the plane.Now, the coefficient of friction between the sandbag and the runway is μk = 0.4, and also theplane’s brakes give an additional retarding force of magnitude 1400 N. So our target for thisproblem is to find how far does the plane go before it comes to stop.Assume, when the plane snags the sandbag, the collision is instantaneous.[Hints Think carefully whether you can apply conservation of momentum or not] Find the speed of the plane and sandbag immediately after the collision.arrow_forwardA man is pushing a refrigerator initially at rest up a 20 degree incline.
