A kid on a bike with a combined mass of 100 kg goes 7 m/s at the top of a hill. The hill has a vertical drop of 50 m. How fast is the kid and bike going when they reach the bottom of the hill?( no friction) 1. c. d. O 27 m/s 23 m/s O 32 m/s O 980 m/s

Question 8 Two horses are used to pull a canal boat as shown in the figure. Each horse produces exactly 1 hp (745.7 W). The boat moves at a constant at a constant velocity of 1.69 m/s. If the angle between the motion of the boat and each of the ropes is 0 = 39.21°, then what is the tension in each rope? (809) A) O697.99 N B) 0540.82 N C) O1138.93N D) O284.73 N E) O569.47 N

A car is accelerated from velocity v1 to v2 in the time period of t . The mass of the car is m. The inclined angle of the hill is α. The distance travelled along the hill is L. The vertical distance travelled is H.  Select the correct equation of the kinetic energy increase of the car ΔKE?_______       A.     B.     C.     D.

A 1000-kg car accelerates from rest to 10m/s in 5 seconds.  (1) Select the formula used to calculate the power required for this acceleration__________       A.     B.     C.     D.

Current Attempt in Progress A fully loaded, slow-moving freight elevator has a cab with a total mass of 1600 kg, which is required to travel upward 40 m in 1.6 min, starting and ending at rest. The elevator's counterweight has a mass of only 870 kg, so the elevator motor must help pull the cab upward. What average power is required of the force the motor exerts on the cab via the cable?

The dog stole the baby's dirty diaper that Kristan had just changed and was getting ready to throw away. The dog weighs 15kg and the diaper weighs 2kg. The dog runs outside and climbs up the stairs to the playhouse where it accidentally steps a little too far in the slide causing the dog to slide down the slide with the diaper in his mouth. The height of the slide is 1.5m high off the ground. What is the change of potential energy of the dog assuming it started at rest and slid all the way to the ground?

Part A The cable of a crane is lifting a 950 kg girder. The girder increases its speed from 0.25 m/s to 0.75 m/s in a distance of 2.3 m. What is the girder's change in kinetic energy? Express your answer with the appropriate units. НА AK Value Units Submit Request Answer
