At time t = 0, a car moving along the +-axis passes through a = 0 with a constant velocity of magnitude vo. At some time later, t₁, it starts to slow down. The acceleration of the car as a function of time is given by: a 2 (t) = { e(t_t₁) -c(t 0 ≤ t ≤t₁ t₁ < t < t₂ where c is a positive constants in SI units, and t₁ < t ≤ t₂ is the given time interval for which the car is slowing down. The goal of the problem is to find the car's position as a function of time between t₁ < t < t2. Express your answers to the following questions using the following as needed: v_ for vo, t_1 for t₁, c, t. (Part a). What is v (t), the velocity of the car as a function of time during the time interval 0 ≤ t ≤t₁? v (t) = (Part b). What is x (t), the position of the car as a function of time during the time interval 0 ≤ t ≤ t₁? x (t) = (Part c). What is v (t), the velocity of the car as a function of time during the time interval t₁ < t
Rocket-powered sleds are been used to test the responses of humans to acceleration. Starting from rest, one sled can reach a speed of 510 m/s in 2.37 s and can be brought to a stop again in 3.15 s. Find the acceleration of the sled while accelerating. Answer in units of m/s2. Find the acceleration of the sled when braking. Answer in units of m/s2.
Assume you are driving a car at a constant speed of 76 km/h. Suddenly you see a deer standing on the highway and you must put on the brakes. Your reaction time (time elapsed between the moment you see the deer and your foot hitting the brakes) is 0.118 s. The brakes provide an acceleration with a magnitude of 4 m/s2, and a direction opposite the initial velocity. How do you find the total distance traveled?
A car drives around a circular track of diameter 161 m at a constant speed of 47.4 m/s. During the time it takes the car to travel 256 degrees around, what is the magnitude of the car s average acceleration? Hint: Do not calculate instantenous accelleration. Instead calculte the average acceleration over the fraction of a complete lap. Average acceleration equals change in velocity divided by change in time, and that this is a two-dimensional situation so you'll have to calculate the x and y components of the average acceleration first and then figure out the magnitude. Remember also that ax = Δvx/Δt and ay = Δvy/Δt. 0 m/s^2 27.91 m/s^2 13.96 m/s^2 9.84 m/s^2
A hot air balloon is moving vertically upwards at a constant rate of 9.0 m/s. As the balloon rises, a package is dropped from the balloon and it takes 5 s to hit the ground. How far did the package fall? Make sure to include a diagram of the physical situation, label known and unknown quantities with units, and coordinate system. Thanks!

An ambulance driver is rushing a patient to the hospital. While traveling at 71.1 km/h, she notices the traffic light at the upcoming intersection has turned yellow. To reach the intersection before the light turns red, she must travel 52 m in 2.17 seconds. What is the magnitude of the minimum acceleration, in m/s2, required to reach the intersection before the light turns red?
Cheetahs can accelerate to a speed of 21.8 m/s21.8 m/s in 2.55 s2.55 s and can continue to accelerate to reach a top speed of 28.6 m/s28.6 m/s .

The Willamette Pass ski area in Oregon was the site of the 1993 U.S. National Speed Skiing Competition. The skiers started from rest and then accelerated down a stretch of the mountain with a reasonably constant slope, aiming for the highest possible speed at the end of this run. During this acceleration phase, the skiers traveled 360 m while dropping a vertical distance of 170 m. What is the fastest speed a skier could achieve at the end of this run?
