- When visiting a friend in Atlanta you decide to drive around the city. You turn a corner and are driving up a steep hill. Suddenly, a small boy runs out on the street chasing a ball. You slam on the brakes and skid to a stop leaving a 50-foot-long skid mark on the street. The boy calmly walks away but a policemen watching from the sidewalk walks over and gives you a speeding ticket. He points out that the speed limit on this street is 25mph. After you recover your wits, you begin to examine the situation. You determine that the street makes an angle of 25◦ with the horizontal and that the coefficient of static friction between your tires and the street is 0.80. You also find that the coefficient of kinetic friction between your tires and the street is 0.60. Your car’s information book tells you that the mass of your car is 1600 kg. You weigh 140 lbs. Will you fight the ticket in court? Please draw a figure with your detailed answer.When visiting a friend in Atlanta you decide to drive around the city.

Please be as detailed as possible with your answer.In 1987, as a Halloween stunt, two sky divers passed a pumpkin back and forth between them while they were in free fall just west of Chicago.The stunt was great fun until the last sky diver with the pumpkin opened his parachute. The pumpkin broke free from his grip, plummeted about 0.5 km, ripped through the roof of a house, slammed into the kitchen floor, and splattered all over the newly remodeled kitchen. From the sky diver’s viewpoint and from the pumpkin’s viewpoint, why did the sky diver lose control of the pumpkin?You want to visit your friend in Seattle and decide to take the train. Unfortunately, you are late getting to the train station. You are running as fast as you can, but 30 meters ahead of you the train begins to pull out. You can run at a maximum speed of 8 m/s and the train is accelerating at 1 m/s². In 50 meters you will reach a barrier. Can you catch up to the departing train? Argue why you should or should not jump onto the moving train?
- The next two questions are going to deal with Superman’s home planet of Krypton. Here on Earth, an athletic man can do a standing jump of about 1.5 m. On the moon, where gravity is 6 times weaker, an athletic man can do a standing jump of about 9.0 m. Originally, Superman was said to be able to “leap tall buildings with a single bound”. Based on this expression, let’s assume that Superman can jump 200 m here on Earth. Using this information, what is the gravitational acceleration, g, of Krypton?On the Martian moon of Phobos, the escape speed is only 11.3 m/s . While standing on Phobos, suppose a person throws a baseball at a speed equal to the escape speed. The figure shows four possible directions in which the person could throw the ball at that speed.In which of these directions will the ball escape from Phobos? Could I please have some direction on how I may approach this? direction A only direction A or B direction A, B, or C direction A, B, C, or D none of theseA skater with mass 66 kg is skating on a horizontal surface at a constant speed 4.2 m/s. There is a ramp ahead, and the skater has just enough speed to make it to the top of the ramp (meaning the speed at the top of the ramp is 0 m/s). What is the height of the ramp in the unit of meters? Use g = 10 m/s2 for the acceleration due to gravity.
