For a mass m falling in air, we assume that the air resistance is proportional to the speed v (t): mv '(t) = mg - kv (t),where g is the acceleration of gravity and k is a positive constant that depends on the geometry of the object.What is v (t) given that v (0) = 0?
A car is traveling at the speed of V m/s on a straight, level road. After the brakes are applied at t = 0, the motion can be approximated by s = (1/112)(t^3) - t^2 + 10t, where s is the distance traveled in meters, and t is the time in seconds. Determine the distance (meters) required for the car to stop.
In Fig, a slab of mass m1 =40 kg rests on a frictionless floor, and a block of mass m2 =10kg rests on top of the slab. Between block and slab, the coefficient of static friction is 0.60, and the coefficient of kinetic friction is 0.40. A horizontal force of magnitude 100 N begins to pull directly on the block, as shown. In unit-vector notation, what are the resulting accelerations of (a) the block and (b) the slab?
Consider a skier heading down a 11° slope. Assume the coefficient of friction for waxed wood on wet snow is μk = 0.10 and use a coordinate system in which down the slope is positive. a.

Most aircraft need an airspeed of about 120 knots (61.7 m/s) to lift off. If a fully laden b-52 starts from rest with an acceleration of 4.16 m/s2, how long a runway does it need to be able to take off?
The block has mass m = 10.6 kg, the ramp is at an angle of θ = 24 degrees, the coefficient of kinetic friction between the block and the ramp is μk = 0.25, and the applied force is F = 150.2 N. What is the acceleration of the block up the ramp, in m/s2?
Consider an airplane whose takeoff speed is 220 km/h and that takes 15 s to take off at sea level.

On July 13, 1977, while on atest drive at Britain’s Silverstone racetrack, the throttle on DavidPurley’s car stuck wide open. The resulting crash subjected Purleyto the greatest “g-force” ever survived by a human—he deceleratedfrom 173 km>h to zero in a distance of only about 0.66 m. Calculate the magnitude of the acceleration experienced by Purley(assuming it to be constant), and express your answer in units ofthe acceleration of gravity, g = 9.81 m>s2.
