A car is traveling at 88 ft/sec when the brakes are applied,
producing a constant deceleration of 11ft/sec2.22ft/sec^2. What is
the distance traveled before the car comes to a stop?
A motorcycle is following a car that is traveling at constant
speed on a straight highway. Initially, the car and the motorcycle
are both traveling at the same speed of 21.5 m/s , and the distance
between them is 60.0 m . After t1 = 5.00 s , the motorcycle starts
to accelerate at a rate of 8.00 m/s2 . The motorcycle catches up
with the car at some time t2.
How long does it take from the moment when...
A motorcycle is following a car that is traveling at constant

A motorcycle is following a car that is traveling at constant
speed on a straight highway. Initially, the car and the motorcycle
are both traveling at the same speed of 18.0m/s , and the distance
between them is 54.0m. (A) How long does it take from the moment
when the motorcycle starts to accelerate until it catches up with
the car? In other words, find t2-t1. (B) How far does the
motorcycle travel from the moment it starts to accelerate...
An unmarked police car traveling a constant 80.0 km/h is passed
by a speeder traveling 135 km/h . Precisely 2.00 s after the
speeder passes, the police officer steps on the accelerator; if the
police car's acceleration is 1.60 m/s2 , how much time passes
before the police car overtakes the speeder after the speeder
passes (assumed moving at constant speed)?
An unmarked police car traveling a constant 95 km/hr is passed
by a speeder traveling 135 km/hr. Precisely 1.00 s after the
speeder passes, the police officer steps on the accelerator; if the
police car’s acceleration is 2.00 m/s2 , how much time passes
before the police car overtakes the speeder (assumed moving at
constant speed)?
An unmarked police car traveling a constant 95km/h is passed by
a speeder traveling 133km/h .
Precisely 1.00 s after the speeder passes, the police officer
steps on the accelerator; if the police car's acceleration is
2.50m/s2 , how much time passes after the police car is passed by a
speeder and before the police car overtakes the speeder (assumed
moving at constant speed)?
A car is traveling at 20 mi/h on good, dry
pavement at 5000 ft elevation. The front-wheel-drive
car has a drag coefficient of 0.30, a frontal area of 20 ft2
and a weight of 2500 lb. The wheelbase is 110 inches
and the center of gravity is 20 inches from the ground,
50 inches behind the front axle. The engine is producing
95 ft-lb of torque and is in a gear that gives an overall
gear reduction ratio of 4.5....
A car of mass 1000kg is traveling in a northward (+y) direction
with a constant speed of 10m/s. It then hits a stationary truck.
The truck is twice as heavy as the car. After the collision, the
car travels in a direction 30 degrees East of North and the truck
travels 60 degrees West of North.
a) What are the final speeds of the car and the truck after
collision?
b) Calculate the change in kinetic energy of the system...
