Problem 1: You are an insurance investigator at the scene of a car accident. From witness descriptions, it is clear that Car A (of mass M_A) started skidding and slid a distance L (which you measure from the tire marks at the scene) and collided with car B (of mass M_B) which was at rest at a stoplight. The two cars after they collided both slid a distance L_slide which you also measure from the scene of the accident. Given the coefficient of kinetic friction between tires and the road, mu_k (as well as M_A, M_B, g, L_slide and L) can you calculate how fast car A was travelling when it started to slide - which would be relevant for determining if car A was speeding before the collision.

help please. If a 1467 kg car, moving at 9 m/s north, hits and sticks to a 2237 kg truck, moving at 10 m/s south, and they travel off together at the same speed, find that speed. Hint: here the masses are moving in opposite directions, so the velocities should have opposite signs. Call North positive and South negative. Use the "hit and stick" or inelastic formula Also, a positive answer would indicate motion to the north and a negative answer would show southward motion - leave positive/negative in your answer.
Two small-sized objects are placed on a uniform 9.00 kg plastic beam 3.00 m long, as shown in (Figure 1). Assume that 1m= 7.75 kg and m2 = 7.55 kg. Part A Find the location of the center of mass of this system by setting x=0x=0 at the left end of the beam. Express your answer in meters. Part B Find the location of the center of mass of this system by setting x=0x=0 at the right end of the beam. Express your answer in meters. Part C Do you get the same result both ways?
Object A traveling east at a certain velocity collides with object B traveling west at lower velocity. Object A has mass in kg and object B has a greater mass in kg. The collsion takes place in one dimension, and is elastic. Taking east to be positive, how do I find the velocity of Object A after the colission?
A car moving at 15 m/s crashes into a tree stops in 1.02 as the mass of the passenger inside is 74 KG Part A. Calculate the magnitude of the average force in newtons that the seatbelt exerts on the passenger in the car to bring him to a halt ?
A block of mass m is being pulled by the string as shown below. The string has a tension T and makes an angle with the horizontal. If the block is initially at rest, find an expression for the velocity of the block after is has been moved a distance d. Your expression should only contain terms such as the tension, the coefficient of kinetic friction, the angle, d, etc. m T 0 Hk
A uniform density sheet of metal is cut into the shape of an isosceles triangle, which is oriented with the base at the bottom and a corner at the top. It has a base B = 43 cm, height H = 25 cm, and area mass density σ. - The horizontal center of mass of the sheet will be located: On the center line. Not enough information to determine. To the left of the center line. To the right of the center line. - The vertical center of mass of the sheet will be located: Below the mid height. Not enough information to determine. Above the mid height. At the mid height. - Write a symbolic equation for the total mass of the triangle. -Consider a horizontal slice of the triangle that is a distance y from the top of the triangle and has a thickness dy. Write an equation for the area of this slice in terms of the distance y, and the base B and height H of the triangle. - Set up an integral to calculate the vertical center of…
a shape is on an x-y axis, beginning at x = 0. The bottom of the shape is 25 cm long and it reaches a height of 20 cm. The shape weights 450 g. The shape has a triangular form, like a wedge. If shape has a uniform density and a uniform width in the z-direction, find the x-component of the center-of-mass.
In order to answer this question, follow the steps provided and remember that the total initial momentum of the system must equal the total final momentum. Also, remember that momentum and velocity are vector quantities so you must specify a negative sign if the motion is to the left. A green truck of mass 2500 kg travels to the right with a velocity vig = 3.7 m/s. The green truck approaches a red truck with mass 1460 kg that is traveling to the left with a velocity of vir = -3 m/s. The trucks collide and stick together after the collision. What is the final velocity, vf of the green-red truck system after the collision. (look at the figure/picture)(a) What was the initial momentum of the green truck before the collision?pgi = 9250 kg m/s(b) What was the initial momentum of the red truck before the collision?pri = -4380 kg m/s(c) What was the total initial momentum of the system of trucks?pTf = 4870 kg m/s (d) What must be the total final momentum of the system after the collision if…
In this problem, we will consider the following situation as depicted in the diagram: A block of mass m slides at a speed v along a horizontal smooth table. It next slides down a smooth ramp, descending a height h, and then slides along a horizontal rough floor, stopping eventually. Assume that the block slides slowly enough so that it does not lose contact with the supporting surfaces (table, ramp, or floor). You will analyze the motion of the block at different moments using the law of conservation of energy. A B y=0 C a. Which word in the statement of this problem allows you to assume that the table is frictionless? b. Where (letter) would the block have the greatest gravitational potential energy? c. Where (location) would the block experience the greatest kinetic energy?
