Question

A car is traveling at 88 ft/s when the brakes are fully applied, producing a constant deceleration of 11 ft/s2. What is the distance covered before the car comes to a stop?

Answer #1

A car is traveling at the rate of 95 ft/sec when the brakes are
applied. The car begins decelerating at a constant rate of 20
ft/sec2.
A. How many seconds elapse before the car stops?
B. How far does the car travel during that time?

A car initially traveling at 29.2 m/s undergoes a constant
negative acceleration of magnitude 2.00 m/s2 after its
brakes are applied
(a) How many revolutions does each tire make before the car
comes to a stop, assuming the car does not skid and the tires have
radii of 0.300 m?
(b) What is the angular speed of the wheels when the car has
traveled half the total distance?
rad/s

A car initially traveling at 25.7 m/s undergoes a constant
negative acceleration of magnitude 1.80 m/s2 after its
brakes are applied.

comes to a stop, assuming the car does not skid and the tires have
radii of 0.320 m?

(b) What is the angular speed of the wheels when the car has
traveled half the total distance?
rad/s

A car initially traveling at 25.7 m/s undergoes a constant
negative acceleration of magnitude 1.50 m/s2 after its
brakes are applied.
(a) How many revolutions does each tire make before the car
comes to a stop, assuming the car does not skid and the tires have
radii of 0.350 m?
(b) What is the angular speed of the wheels when the car has
traveled half the total distance?

A car initially traveling at 28.2 m/s undergoes a constant
negative acceleration of magnitude 2.00 m/s2 after its
brakes are applied.
(a) How many revolutions does each tire make before the car
comes to a stop, assuming the car does not skid and the tires have
radii of 0.320m?
Answer: 98.9
(b) What is the angular speed of the wheels when the car has
traveled half the total distance?
Answer: ?

When the brakes are applied, a car decelerates at 0.7
meters per second per second. Use antiderivatives to determine the
stopping distance for a car traveling 100 km/hr. That is, how far
does this car travel between the instant the brakes are applied and
the instant it comes to a complete stop. Be careful with your
units!

A car is traveling at 15 m/s on a horizontal road. The brakes
are applied and the car skids to a stop in 4.0 s. The coefficient
of kinetic friction between the tires and road is:
Select one:
a. 0.38
b. 0.69
A ball is thrown straight up with a speed of 36.0 m/s. How long
does it take to return to its starting point?
Select one:
a. 7.20 s
b. 10.2 s
c. 14.7 s
d. 11.0 s
e....

A car traveling at 45 miles per hour is brought to a stop, at
constant deceleration, 132 feet from where the brakes are
applied.
a) How far has the car moved when its speed has been reduced to
30 miles per hour?
b) How far has the car moved when its speed has been reduced to
15 miles per hour?
c) What is the car's rate of deceleration?

A car of mass 772 kg is traveling 26.4 m/s when the driver
applies the brakes, which lock the wheels. The car skids for 4.47 s
in the positive x-direction before coming to rest.

(a)
What is the car's acceleration (in m/s2)? (Indicate
the direction with the sign of your answer.)
m/s2
(b)
What magnitude force (in N) acted on the car during this
time?
N
(c)
How far (in m) did the car travel?
m

A car traveling 57.8 km/h is 21.7 m from a barrier when the
driver slams on the brakes. The car hits the barrier 2.22 s later.
(a) What is the car's constant deceleration magnitude before
impact? (b) How fast is the car traveling at impact?
