DECORE MI ts. Using Newton's second law to calculate the acceleration of a key hanging in a car. You tape one end of a piece of string to the ceiling light of your car and hang a key with mass m on the other end of the string, A protractor taped to the light allows you to the angle the string makes with the vertical. Your friend drives the car while you make measurements. When the car has a constant acceleration with magnitude a toward the right, the string hangs at rest (relative to the car), making an angle ß with the vertical. (a) Derive an expression for the acceleration a in terms of the mass m and the measured angle B. (b) In particular, what is a when B = 45°? When B=0? Show your work that leads to your answer. Explain each step in your work to get the full credit. The equation with no ts. Calculate the magnitude and explanation will get your answer zero point. (c) bo direction of the total force acting on your body when the measured angle B is 45 degree or B = 45°. Assume the mass of your body is 100 kg. You may use the free-body diagram. Show your work that leads to your answer. Explain each step in your work to d

You have put a sonar device at the top of a frictionless inclined plane, as shown in the diagram below. That device allows you to measure the distance an object is from the device, as well as the speed and the acceleration of that object. If we decide that the origin (h = 0) is at the sonar device, we want to know what the height change is as we slide down the incline. 0 For an angle below the horizontal of 6.46, we see that our object has slid a distance 1.13 m, as measured along the incline itself. Calculate the height change in meters - and report your answer as a negative number. (This value would be useful for calculating the change in gravitational potential energy, as we will do in the lab.) h=o 10% O i 26 QUATU 99+ hp X 55 83°F 3:11 PM 10/16/2022 Ctrl 0

The radius of the curve is 150 m. Compute the acceleration at the moment the train speed reaches 50.0 km/hr. Assume the train continues to slow down at this time at the same rate.
