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.

A rock is thrown straight up. At the top of the trajectory, the velocity is momentarily zero. Does this imply that the force acting on the object is zero? Explain your answer.
Try the following experiment away from traffic: where you can do it Safely. With the car VOU are driving moving slowly on a Straight, level road, shift the transmission into neutral and let the car coast. At the moment the car comes to a complete slop, step hard on the ln.ike and notice what you feel. Now repeal I he same experiment on a fairly gentle, uphill slope. Explain the difference in what a pet son tiding in the car feels in the two cases. (Brian Popp suggested the idea for this question.)
A 200-kg box slides down a frictionless plane that is angled at 20 degrees with respect to the horizontal. Compute for its acceleration in units of m/s2.
A pilot is flying a plane at 220 m/s and an altitude of 500 meters. If she needs to deliver supplies via air drop, how far away from the target should she release the cargo? The cargo's parachute slows the average acceleration of gravity to 0.75 m/s2. Answer in kilometers.(In reality, a parachute significantly reduces the terminal velocity, so it won't accelerate very long. But let's keep it simple and assume the cargo accelerates the whole way.)

A woodpecker’s brain is specially protected from large accelerations by tendon-like attachments inside the skull. While pecking on a tree, the woodpecker’s head comes to a stop from an initial velocity of 0.600 m/s in a distance of only 2.00 mm. (a) Find the acceleration in meters per second squared and in multiples of g, where g = 9.80 m/s2. (b) Calculate the stopping time. (c) The tendons cradling the brain stretch, making its stopping distance 4.50 mm (greater than the head and, hence, less acceleration of the brain). What is the brain’s acceleration, expressed in multiples of g?
An object of mass m falls from rest under gravity subject to an air resistance proportional to its speed. Taking the y axis as positive down, show that the differential equation of motion is m(dv/dt) = mg − kv, where k is a positive constant. Find v as a function of t, and find the limiting value of v as t tends to infinity; this limit is called the terminal speed. Can you find the terminal speed directly from the differential equation without solving it? Hint: What is dv/dt after v has reached an essentially constant value? Consider the following specific examples of this problem.(a) A person drops from an airplane with a parachute. Find a reasonable value of k.(b) In the Millikan oil drop experiment to measure the charge of an electron, tiny electrically charged drops of oil fall through air under gravity or rise under the combination of gravity and an electric field. Measurements can be made only after they have reached terminal speed. Find a formula for the time required for a drop…
