QUESTION 4 Compare the case of an object sliding down a ramp and the same object rolling without slipping down a ramp with the same slope, and from the same height. Which of the following is true? a. The sliding object reaches the bottom faster, but the increase in total kinetic energy is the same b. Both objects reach the bottom at the same time, but the rolling one has more kinetic energy .The sliding object takes longer to reach...

Due Fri 05/10/2019 11:59 pm Sasha and Alyssa are walking around a new town and are super hungry. They spot an In N Out sign at a beari of S45° E from their current location. There are two streets from here, one with a bearing of S5 W and another with a bearing of S60° E. Sasha believes the S5 W route will be faster so she starts down that path, while Alyssa thinks otherwise and uses the other street....

(1 point) Ken and Billy both live in the same neighborhood, and work at the university. Ken drives to work, Billy rides his bicycle. You - a budding statistician - have been asked to settle an argument. Ken believes that more often than not, his commuting time via his drive is less than Billy's. Billy believes that this is not so, due to traffic volume and traffic lights. Over the period of one month, the statistician randomly selects eight days...
It is said that walking at a comfortable speed
2. It is said that walking at a comfortable speed involves a pendulum-like motion of your legs. We want to see how good this claim is quantitatively. (A) First we are going to predict your gait. The legs are not a SIMPLE pendulum, in that all the mass is not concentrated at your foot, but is distributed. For such a pendulum the period T is given by the equation T = 2π √(I/mgL) where I is the moment of inertia. ...

Please explain to me in detail
1. A moving truck has momentum. If it moves four times as fast, its momentum is as much. 2. Two carts, one three times as heavy as the other, move down a hill at the same speed. Compared to the lighter cart, the momentum of the heavier cart is as much. 3. A bus is traveling at highway speeds when the momentum of an unlucky bug is suddenly changed as it splatters into the...

1. During World War I, Germany used a "Big Bertha" cannon to hurl shells into Paris 30 miles away. This gun also had a long barrel. What is the reason for using a long barrel in these guns? 2. Consider two less-than-desirable options. In the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. In the second option you are driving 30 mph and crash head-on into a stationary brick wall. In...

1a. You are driving down the street at a constant speed of 60mph. Draw a graph of distance versus time over the course of 4 hours. b. How would you use the graph to determine the rate (speed in mph) at which the car is traveling (assuming you did not already know the answer)? Hint: What is the slope for the graph in part A? What does the term slope mean? c. Now draw a new graph (still distance vs....

A block slides down a smooth ramp (without friction) of height h. The block started at rest. It reaches a speed v at the bottom of the ramp. What would the height of the ramp need to be to reach a speed of 2u? 3h 4h 2 h 1.41 h 6 h h 0/1 pts Question 2 A block slides down a rough ramp (with friction) of height h. The block started at rest.

2) Suppose the block from the previous question is launched with the same initial speed vo on the following frictionless ramps. In each case, state whether the magnitude of the net work done on the block from the bottom to the top of the ramp is greater than, less than, or equal to the magnitude of the work done on the block in Question 1. Explain your answer in each case. Case a: the ramp is steeper (α > θ)...
