Solve question 10

QUESTION 10 A dart of 44-g mass is loaded 28 cm into a vertically coiled spring and then is released. The spring has a spring constant of 305 N/m and negligible mass. What maximum height reached by the dart? Round to the nearest tenth. QUESTION 11 A cart travels along a frictionless roller coaster track. At the top of a hill the roller coaster is 11.8 m above the ground and is traveling at 6.5 m/s. The cart reaches the ground and ascends a hill that is 3 high. What is the speed of the cart at this point? Round to the nearest tenth. QUESTION 12 A 782 kg car with an initial speed of 38 m/s is observed to coast up a hill to a height 24 m above its starting point, how much thermal energy was generated by friction? Round to the nearest whole number.
