A student releases a 3.9kg cart from the top of ramp and starts a stopwatch. The length from the front of the cart to the end of the ramp and the distance from the end of the ramp to the stopper are shown. Neglect backwards friction and drag and assume the cart does not lose speed transitioning from the ramp to the floor. What is the cart's acceleration on the ramp? unit | (magnitude) What is the cart's acceleration on the floor? 130cm unit (magnitude) How long does the cart take to reach the end of the ramp? 5° 200cm unit (timed from the release) How fast is the cart traveling as it hits the stopper? unit How long does the cart take to reach the stopper? unit (timed from the release) cannot be detern check answers challenge ne Calculator ound = 343m/s cant figures Rain to stop e here to search ACC t;320

Ignoring air drag, the rocket will travel a distance of m further before reaching its maximum height. (Record your answer in the numerical-response section below.) Your answer: 0000 11. A toy snowmobile has a mass of 21.0 kg and a velocity of 94.0 m/s directed at 10.0° N of E. The component of the snowmobile's momentum in the North direction is kg-m/s. (Record your answer in the numerical-response section below.) Your answer: 0000 Use the following information to answer the next three questions Object 1 with a mass of 4.80 kg, moving right at a speed of 8.60 m/s along a frictionless surface, collides head-on with Object 2 with a mass of 3.70 kg moving left at a speed of 10.8 m/s. After the collision, the Object 1 is moving left at 2.20 m/s. 12. The final speed of object 2 would be m/s. Answer to 3 sig digs. (Record your answer in…

7 on 1 Q A Z @ 2 A package of mass m is released from rest at a warehouse loading dock and slides down the 2.5-m-high, frictionless chute to a waiting truck. Unfortunately, the truck driver went on a break without having removed the previous package, of mass 2m, from the bottom of the chute.
