C. -mgh D. mgh+ m2 E. Zero 8. What is the speed of a jet coaster starts from resta speed of a jet coaster starts from rest and straight down the steep friction-free slope. Total mass of the vehicle 350 k u dine passenger and the rails are frictionless gravitational acceleration is 9.80 m/s downward. V=? m = 350kg a = 1.80 m/s v=Votmy ngh=/m 2² - 0 + 350 kgx 9.80 m/s' = 3430 m/s 350(9.80) {(350)(0){mgh Two children sit on a seesaw. One has a mass of 30.0 kg and sits 1.00 m from the pivot point. If the other child sits 1.35 m from the pivot point on the other side to balance the seesaw, what is the mass of the other child? Assume the seesaw has negligible mass. m = 300kg x= 1.00m x=1.35 hland
