- Your forehead can withstand a force of about 6.0 kN before fracturing, while your cheekbone can only withstand about 1.3 kN. If a 140g baseball strikes your head at 30 m/s and stops in 0.0015 seconds, what is the magnitude of the balls deceleration? Express your answer in meters per second squaredThe centripetal force of an object of mass m is givenby F(r) =mv^2/r, where v is the speed of rotation and ris the distance from the center of rotation.a. Find the rate of change of centripetal force withrespect to the distance from the center of rotation.b. Find the rate of change of centripetal force of anobject with mass 1000 kilograms, velocity of 13.89m/s, and a distance from the center of rotation of200 metersA 2110 kg car traveling at 8.4 m/s collides with a 2730kg car that is initially at rest at the stoplight. The cars stick together and move 3.30 m before friction causes them to stop. Determine the coefficient of kinetic friction between the cars and the road, assuming that the negative acceleration is constant and that all wheels on both cars lock at the time of impact.
- You are driving a car at a constant speed of 14.0 m/s along a straight level road. As you approach anintersection, the stoplight turns red and you slam on breaks and the wheels lock and you skid to a stop in25.0 m. What is the coefficient of kinetic friction between your tires and the road?An empty box is travelling on the conveyor with 0.2 m/s, then 12 kg package is dropped into this box with 1 m/s speed. When dropped, package and box are immediately sticked together. Friction coefficeient between the box and the conveyor is μk = 0.2 . After the package dropped, package and box start sliding on the conveyor for some distance, d for t(sliding) amount of time. Determine the distance, d.Question 9. Traveling at a speed of 16.1 m/s, the driver of an automobile suddenly locks the wheels by slamming on the brakes. The coefficient of kinetic friction between the tires and the road is 0.590. What is the speed of the automobile after 1.21 s have elapsed? Ignore the effects of air resistance. Ans: 9.1 m/s
- After seeing a giant rock rolls into the highway, the driver slams on the brake and steers the truck onto an emergency escape ramp. The angle between the ramp and the horizontal is 0 = 15.0', and the magnitude of the velocity i of the truck is 30.0 m/s right after entering the ramp. If the coefficient of kinetic friction µk (for the ramp) is 0.720, then how far along the ramp does the truck travel until it stops? *Use work-energy theorem to answer this question and assumed that the wheels of the truck are locked (not rolling). *Include a free body diagram to solve this problem.In the figure, the coefficient of kinetic friction between the block and the surface is μ and the block is moving with constant velocity.

When you arrive, you clearly want to do some experiments to learn more about this world. You begin with some simple kinematics and measure the time t for an object thrown directly up with velocity vi to return to your hand. With this information, you find that the acceleration due to gravity gi s much lower than on Earth. a)Find the mass of the planet mpin terms of vi, t, r, and any necessary constants. b) You decide to orbit the planet in your spacecraft at a distance Rabove the surface of the planet. Find the time required to complete one orbit in terms of R, r, vi, t, and any necessary constants. c) FInd the escape velocity ve–the initial velocity necessary for an object to barely escape the gravitational pull of the planet. Express your answer in terms of vi, r, t,and any necessary constants.
