The brakes are applied to a car traveling on a dry, level highway. A typical value for the magnitude of the car's acceleration is 4.95 m/s2. If the car's initial speed is 27.0 m/s, how long does it take to stop and how far does it travel, starting from the moment the brakes are applied

By shooting water from its rear, a squid can provide itself with jet propulsion. Suppose a squid launches itself vertically upward from rest with constant upward acceleration for 0.890 s and travels a vertically upward distance of 2.72 m.  The squid then turns off its jets and continues its flight in free fall.  (a) What is the magnitude of the squid’s acceleration during the time it is jetting? (b) How long does it take the squid to reach its maximum height while in free-fall after jetting? (c) What maximum height did the squid attain?

A racing enthusiast claims that his sports car will accelerate from rest to a speed of 40.0 m/s in 8.10 s. (a) Determine the magnitude of the average acceleration of the car (in m/s2). m/s2 (b) Assume that the car moves with constant acceleration. Find the distance (in m) the car travels in the first 8.10 s. m (c) What is the speed of the car (in m/s) 10.0 s after it begins its motion if it continues to move with the same acceleration? m/s

An object is subject to a constant acceleration of 4.16 m/s2 in the positive x direction. If it is initially at rest, what is its displacement in the x-direction at t = 8.99 s?

A motorcycle has a constant acceleration of 3.95 m/s². Both the velocity and acceleration of the motorcycle point in the same direction. How much time is required for the motorcycle to change its speed from (a)19.4 to 29.4 m/s, and (b)49.4 to 59.4 m/s? (a) Number i Units (b) Number i Units

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 motorist drives north for 32.0 minutes at 65.0 km/h and then stops for 15.0 minutes. He then continues north, traveling 130 km in 2.20 h. (a) What is his total displacement? km (b) What is his average velocity? km/h

A snowboarder on a slope starts from rest and reaches a speed of 4.4 m/s after 9.4 s. (a) What is the magnitude of the snowboarder's average acceleration in m/s2(b) How far does the snowboarder travel in this time in m

A person hits a trampoline while moving downward with a speed of 9 m/s and rebounds a short time later with roughly the same speed upward. If the person is in contact with the trampoline for about 1.8 s, what are the magnitude and direction of the person’s average acceleration during this time interval? (Hint: You can ignore the effects due to gravity

A motorist drives north for 37.0 minutes at 98.0 km/h and then stops for 15.0 minutes. He then continues north, traveling 130 km in 1.90 h. (a) What is his total displacement? km(b) What is his average velocity? km/h
