Fill in your choice below, then EXPLAIN your reasoning in the 'Rationale' section: A traffic officer can determine if a car wasspeeding by looking at how long the skid marks are on the road. A standard VW Golf GTi will normally skid 8 m if it travelsat 60 km/h and the driver suddenly 'locks' the brakes. How far will it skid if it was travelling at 180 km/h instead of 60 km/h?O A. 72 mOB. 16 mO C. 24 mO D. 144 m

Suppose that the truck's mass is 4000 kilograms, and the car's mass is 2000 kilograms. Assume that the truck slows down by 5 m/s during the collision. Based off of your intuition, how much speed does the car gain during the collision? (Assume the logic that the car reacts more in the collision, and note that the truck has twice the mass of the car). Explain your intuitive reasoning.
Hi, please show full solutions and also explain how you get the answers in physics terms so it's understandable. The correct final answers are written beside too. Thank you. A slider approaches a ramp that is sloped up at an angle of 10.0º at a velocity of 6.0 m/s. The coefficient of friction between the slider and the ramp is 0.2. How far up the ramp does the slider slide? (5.0 m)
A box of mass 12 kg is pulled at a constant velocity with a cord that makes the angle 32 degrees as shown in the sketch. If the coefficient of kinetic friction between box and the surface at which it is sliding on is 0.21, and tension in the string is 13 N, what is the value of kinetic friction force?

In the picture below a block is at a height, h above point B with an initial velocity of 1.33m/s to the right. At point C the height is h/3 above B and a frictional force begins acting on the block at C. If the block stops 4.58 meters from point C and the kinetic coefficient of friction on the block was 0.313, what was the initial height of the block?
8. Rotation A hollow ball with mass mand radius r (I = (2/3)mr about the center or / = (5/3)m about the edge) rolls without slipping down the ramp shown at right.
Use the worked example above to help you solve this problem. A car travels at a constant speed of 35.0 mi/h (15.6 m/s) on a level circular turn of radius 40.0 m. What minimum coefficient of static friction, ?s, between the tires and the roadway will allow the car to make the circular turn without sliding?
Consider the system in the picture below: a cart of mass M with a static friction coefficient u is connected through a massless string to a hanging mass m. M is a capital letter, m is lower case. Write them as such, or vour equations will be confusing, M We want to find the maximum value of the hanging mass m such that the system is in equilibrium. 1. Free body diagram (FBD): Draw a FBD for each: the Cart and the hanging mass. Clearly show all the forces. 2. Clearly write the equilibrium equations for the cart in the horizontal and vertical direction. 3. Clearly write the equilibrium equation for the hanging mass. 4.

Can you help me with this, I copied the given problem stuff below, and posted screenshots of all 3 parts as 2 screenshots, can you make the answers clear. A relief airplane is delivering a food package to a group of people stranded on a very small island. The island is too small for the plane to land on, and the only way to deliver the package is by dropping it. The airplane flies horizontally with constant speed of 483 km/hour at an altitude of 975 m . The positive x and y directions are defined in the figure. For all parts, assume that the "island" refers to the point at a distance D from the point at which the package is released, as shown in the figure. Ignore the height of this point above sea level. Assume that the acceleration due to gravity is g = 9.80 m/s^2
9. If a passenger vehicle travels in a circular path at too high a speed, it can tip over. The image below shows a vehicle beginning to tip over. A group of students investigated the speed at which a passenger vehicle will begin to tip over by using a remote- control toy car. The students drove the car around circular paths of various known radii, at such a speed that it was just starting to tip for each radius. They timed the period of the cars motion and used the period to calculate the 'tipping speed' (the speed at which the toy car begins to tip over) of the car. The graph below shows the data collected by the students: Speed at which toy car begins to tip over (m s'¹') 14 12 10 8 TESTO 0 2 3 Radius (m) 5 6 7 Page 11
You are riding on a roller coaster, and for some reason you are sitting on a scale. The roller coaster is moving at all times during the ride, though its velocity varies. The roller coaster track is shown in the figure below. When you are midway between points A and B on the roller coaster, the roller coaster is speeding up. The scale reading is: RollerCoaster.PNG O Smaller than your actual weight O Equal to your actual weight O Larger than your actual weight O There is not enough information to tell
