- YOU MUST ONLY USE ENERGY CONCEPTS TO COMPLETE THE PROBLEMS BELOW. 1. A toy truck with a mass of 78g is travelling at 15.5m/s on a rough surface. If the car is subject to a friction force of 25N, how far will it travel while slowing down to a speed of 2.5 m/s?A 0.8 Kg ball is released from rest from point A and it hits a spring at point B, as shown in the figure below. Spring constant is 310 N/m. Calculate change in the length of spring? (please type all steps of your solution and show the formulas you have used)As shown here, a small block is released from rest at the top of a ramp. It goes over a loop, and then hits a spring. Which type(s) of energy are present at each of the following points along its path (SELECT ALL THAT APPLY) * GPE KE SPE There is zero energy at this point At the top of the ramp, when it is released from rest As it moves over the top of the loop When the spring brings it to a momentary stop GPE KE SPE There is zero energy at this point At the top of the ramp, when it is released from rest As it moves over the top of the loop When the spring brings it to a momentary stop
- Mass question a 0.125 kg mass is placed on a vertically oriented spring that is stretched 0.32 meters from it equilibrium position. If the spring constant is 250 N/m, how fast will the mass be moving when it reaches the equilibrium position? Give answer in units of m/s.7. The cart, in the diagram below, travels .80 m down the ramp with uniform acceleration in 1.5 seconds. The initial velocity(v.) is 0 m/s. You must show work. Determine the following. If answer requires a calculation, you must show work. The initial velocity(v.) is 0 m/s. a. Average Velocity b. Acceleration c. The dots in the strips below represent the position of the cart as it rolls down the .80- meter-long ramp. The time intervals between the dots are equal. Which of the strips best represents the motion of the cart down the ramp? Justify your choice. d. Which two strips represent an object moving at constant velocity? Justify your answer.Mike's car, which weighs 1,000 kg, is out of gas. Mike is trying to push the car to a gas station, and he makes accelerate 0.05 m/s/s. Using Newton's Second Law, you can compute how much force Mike is applying to the car. If the gas station is 200 meters away and the friction force against him is exactly equal to the force applied in part a, how much work did Mike do?
