A brake is applied to a car traveling at a constant speed of 25 m/s. If the deceleration caused by the braking action is 5 m/per second squared, find the time before the car stops.
Determine the distance traveled before the car stops, IF the car stops at t = 5 seconds.
a. 52.5 m
b. 62.5 m
"A car accelerates from rest and travels for 4.98 s with a uniform acceleration of +1.50 m/s^2. The driver then applies the brakes, causing a uniform acceleration of -1.99 m/s^2. If the brakes are applied for 3.06s, how fast is the car going at the end of the braking period? And how far has the car gone?"
To pull a car from a ditch, the driver ties one end of a rope to the car and the other to a tree 12.5 m away. Driver then pulls sideways from the midpoint of the rope with a 475 N force.
How much force exterted on the car when the rope has been pulled 75 cm to one side?
Hi, I need some assistance with the following questions:
Question: At the average rate of 15 m/s^2. How much time does it take for the complete increase in speed?
a. 0.25 s
b. 4.0 s
c. 0.0577 s
d. 17.3 s
e. 8.0 s
Question: A car traveling 20 m/s is able to stop in a distance d. Assuming the same brakingforce, what
According to recent test data, an automobile travels 0.250 miles in 19.9 seconds , starting from rest. The same car, when braking from 60.0 mi/h on dry pavement, stops in 146 ft. Assume constant acceleration in each part of the motion, but not necessarily the same acceleration when slowing down as when speeding up.
Your car is stuck in a mud hole. You are alone, but you have a long, stong rope. Having studied physics, you tie the rope tautly to a telephone pole and pull on it sideways.
a) Find the force exerted by the rope on the car, when the angle theta is 3 degrees, and you are pulling with a force of 400, but the car does not move.
28-A 7.0 g bullet is fired into a 1.5 kg ballistic pendulum. The bullet emerges from the block with a speed of 200 m/s, and the block rises to a maximum height of 12 cm. Find the initial speed of the bullet?

Please do not include your response in a .pdf format, but Word documents are okay. Thanks!
Here is the actual problem:
A 1000 kg car pushes a 2000 kg truck that has a dead battery. When the driver steps on the accelerator, the drive wheels of the car push against the ground with a force of 4500 N.
(a) What is the magnit
Need help with this assignment... I am very confused on how to do it. Please show all work and fill out the worksheet below.
1. Generate a scatterplot. The variables will be weights of cars (x) and the corresponding braking distances (y).
2. Using the prediction procedure, find the best predicted braking dist
