- Suppose you are driving a car at a high speed. Why should you avoid slamming on your brakes when you want to stop in the shortest possible distance? (Newer cars have antilock brakes that avoid this problem.)arrow_forwardA seaplane of total mass m lands on a lake with initial speed vii. The only horizontal force on it is a resistive force on its pontoons from the water. The resistive force is proportional to the velocity of the seaplane: R=hv. Newtons second law applied to the plane is bvi=m(dv/dt)i. From the fundamental theorem of calculus, this differential equation implies that the speed changes according to vivdvv=bm0tdt (a) Carry nut the integration to determine the speed of the seaplane as a function of time.

- The physics of circular motion sets an upper limit to the speed of human walking. (If you need to go faster, your gait changes from a walk to a run.) If you take a few steps and watch what's happening, you'll see that your body pivots in circular motion over your forward foot as you bring your rear foot forward for the next step. As you do so, the normal force of the ground on your foot decreases and your body tries to "lift off" from the ground. A. A person's center of mass is very near the hips, at the top of the legs. Model a person as a particle of mass m at the top of a leg of length L. Find an expression for the person's maximum walking speed vmax Express your answer in terms of the variables L and appropriate constants. b.)Evaluate your expression for the maximum walking speed of a 70 kg person with a typical leg length of 70 cm . Give your answer in m/s. c.) Give your answer in mph.arrow_forwardA hockey puck (mass = 2 kg) leaves the players stick with a speed of 22 m/s and slides on the ice before coming to rest.

Which statement best explains why the person is less likely to be injured when landing on soft sand than on concrete? Select all that apply. a. The upward acceleration of the person in the sand is less than on concrete, thus the force that the sand exerts on the person is less. b. The person sinks into the sand, increasing the stopping distance. c. The concrete can exert a greater force than the sand. 2)You are inside a car that is speeding up, and you notice a book on the seat next to you starting to slide back. What is happening? a. Not enough information is given to answer the question. b. The sum of the forces on the book is 0, but is looks like it still accelerating because Newton's 2nd Law doesn't apply in this situation. c. The seat is exerting a horizontal force on the book pointing backwards.. 3)A person pushes a 8 kg crate, exerting a 64 N force on it, but the crate’s acceleration is only 5 m/s2.…arrow_forward
