- 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?The standing vertical jump is a good test of an athlete’s strength and fitness. The athlete goes into a deep crouch, then extends his legs rapidly; when his legs are fully extended, he leaves the ground and rises to his highest height. It is the force of the ground on the athlete during the extension phase that accelerates the athlete to the final speed with which he leaves the ground. A good jumper can exert a force on the ground equal to twice his weight. If his crouch is 60 cm deep, how far off the ground does he rise?Two buckets of sand hang from opposite ends of a rope that passes over an ideal pulley. Onebucket is full and weighs 120 N; the other bucket is only partlyfilled and weighs 63 N. (a) Initially, you hold onto the lighterbucket to keep it from moving. What is the tension in the rope?(b) You release the lighter bucket and the heavier one descends.What is the tension in the rope now? (c) Eventually the heavierbucket lands and the two buckets come to rest. What is the tension in the rope now? Show your work and explain
- A 620 kg car pulling a 495 kg trailer accelerates forward at a rate of 2.20 m/s2. Assume frictional forces on the trailer are negligible. Ignore air drag. (c) What is the force (in N) exerted by the trailer on the car? Magnitude: Direction: (forward or backward)An object with a mass of 4kg lies on a rough plane inclined at 20 degrees to horizontal. A force of 35N is applied parallel and up the plane. The object accelerates at 2.5m/s^2. What is the Uk between the object and planeA crate remains stationary after it has been placed on a ramp inclined at an angle with the horizontal. Which of the following statements must be true about the magnitude of the frictional force that acts on the crate? O It is least equal to the weight of the crate. O It is equal to n. O It is larger than the weight of the crate. O It is greater than the component of the gravitational force acting down the ramp. O It is equal to the component of the gravitational force acting down the ramp.
