PLEASEEE SOOON
(Three questions)
1.) Bailey is pulling Dillon on a sled in the snow at a constant velocity of 1 m/s. If she is pulling with 250 N perfectly horizontally, and Dillon and the sled have a combined mass of 90 kg, what is the coefficient of friction between the sled and the snow?
2.) Juan and Michael are paddling a canoe in a lake. The total mass of the guys and the canoe is 180 kg. They are providing a paddling force of 450 Newtons and the water is providing a resistance of 375 Newtons. A) What is the acceleration of the canoe? B) If they start from rest, how fast will they be moving in 6 seconds? C) How much distance will they cover in that 6 seconds?
3.) Oscar is driving his 1000kg car to school. He has to stop at the cross walk by the gym, so he puts on his brakes. His car goes from 15 meters/ second to a stop in 5 seconds. How much force did his brakes exert on the car?
