- a 3kg object is initally moving northward at 15m/s. then a force of 15N, towards the east, acts on it for 3.1 seconds. at the end of the 3.1 seconds, what is the magnitude of the objects final velocity?Your friend’s car has broken down, so you volunteer to push it with your own car to the nearestrepair shop, which is 2.0 km away. You carefully move your car so that the bumpers of the two carsare in contact. You then slowly accelerate to a speed of 2.5 m/s over the course of 1.0 min. The massof your friend’s car is 1.2 x 10 ^3 kg. Assume negligible friction.a) Calculate the normal force between the two bumpers. b) You then maintain a speed of 2.5 m/s. How long does it take you to reach the repair shop? c) Sketch the shape of a velocity time graph for the entire motion. d) Sketch the shape of a position time graph for the entire motion.The Avengers are having a strength competition. The Hulk is tossing 1.20 x 104 kg busses so they slide on their roofs across a grassy field. The coefficient of friction between the busses and the grass is 0.185. The contestants have to use their strength to stop the bus...shortest stopping distance wins. Hawkeye steps up first. Hulk throws the bus with a velocity of 8.50 m/s[W]. Hawkeye jumps in and applies a stopping force of 4.00x103 N. Black Widow is next. Hulk throws the bus with a velocity of 8.25 m/s[W]. Black Widow remembers her physics class and instead of jumping in front of the bus, she drops a 6.00 x 103 kg steel beam onto it to increase the mass and therefore the friction force. Which bus stops in the shortest distance? Be sure to show all your work, use GRASP, and good problem solving form...and, don’t forget to include good F.B.D.s. This is one question please include as many steps as you can thank you!
