4. [25 points] Figure below shows a simple accelerometer designed to measure the centripetal acceleration of a car going around a bend following a circular path. The two ends A and B are fixed to the car. The mass M is free to move between the two springs. The needle attached to the mass moves along a scale to indicate the acceleration. In one instance a car travels around a bend of radius 24 m in the direction shown in Figure below. The speed of the car is 45 km/h. a. State and explain the direction in which the pointer moves from its equilibrium position. b. (i) Calculate the acceleration that would be recorded by the accelerometer. (ii) The mass M between the springs in the accelerometer is 0.35 kg. A test shows that a force of 0.75 N moves the pointer 27 mm. Calculate the displacement of the needle from the equilibrium position when the car is travelling with the acceleration in part (i)

2. A circular rigid body of mass m, radius R and radius of gyration k is released from stationary in an incline plane of incline angle $\theta$ and coefficient of friction $\mu$. Determine the normal reaction force, friction force, linear and angular accelerations when it is in (1) pure rolling motion. (10%) (2) rolling with slipping motion. (10%) (3) Compare a cylinder (radius of gyration k = 1/$\sqrt{2}$) and a hoop (k = 1) of the same mass and the same radius, which one travels faster along the incline plane? (10%) Indicate what kind of motion condition (pure rolling or rolling with slipping) you use.

Mika has purchased the insurance policy from an insurance company to cover the value of his new car in case if it gets totaled for the price of $1500 per year. Mika's car worth $21000 and the probability of him totaling the car during the length of the policy is estimated to be 0.1%. Let X be the insurance company's profit. Answer the following questions: 1. Create the probability distribution table for X: X\outcome\profit $x\P(X = x) car is totaled car is not totaled 2. Use the probability distribution table to find the following: a. $E[X] = \mu_x = $\text{ dollars. (Round the answer to 1 decimal place.)} b. $SD[X] = \sigma_x = $\text{ dollars. (Round the answer to 1 decimal place.)}
