- Tom used 100N of force to drag a 10kgs of rocks up a 15 degree hill. There is an initial velocity of 1.5 m/s. The coefficient of kinetic friction is 0.40 and the rocks is dragged 7.5m. Find the work done in gravity? The work done by friction? The work done by Tom? The change in KE? The speed of the rocks after it is dragged 7.5m?A 65.0-kg file cabinet of is sliding down a rough ramp for a distance of 5.00 m as shown. The friction force on the box is 75.0 N. During this process, what is the work done on the cabinet by its own weight, in Joule? Use g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.A. Find friction. B. Find Gravity.
- Suppose a car approaches a hill and has an initial speed of 106 km/h at the bottom of the hill. The driver takes her foot off of the gas pedal and allows the car to coast up the hill. a. If the car has the initial speed stated at a height of h = 0, how high, in meters, can the car coast up a hill if work done by friction is negligible? b. If, in actuality, a 750-kg car with an initial speed of 106 km/h is observed to coast up a hill and stops at a height 21.5 m above its starting point, how much thermal energy was generated by friction in J? c. What is the magnitude of the average force of friction, in newtons, if the hill has a slope 2.1° above the horizontal?An object of mass m and initial velocity vi is sliding along a frictionless plane. It then goes upan incline, which does have friction, that is raised up by an angle θ above the horizontal. Howmuch energy needs to be released to reduce the object to 1/4 of its original speed? Express youanswer in terms of m, vi, θ, and the distance d traveled along the ramp.Topic: Work and Kinetic Energy. provide given, find, a diagram (if necessary) and show complete solution. thank you
