Consider a car driving at constant velocity. The force of friction acting on the car in Newtons is:
f = 300 + 1.8 v^2 where v is in m/s. The first term is due to friction between the tires and the road; the second term is air drag.
a. Find the magnitude of f when v = 50 miles/h.
b. Find the magnitude of f when v = 65 miles/h
c. Given your answers above, describe an advantage to driving at 50 miles/h instead of 65 miles/h.
A 50 kg ballet dancer stands on her toes during a performance with four square inches (26.0 cm2) in contact with the floor. What is the pressure exerted by the floor over the area of contact (a) if the dancer is stationary and (b) if dancer is lea..

Two negative point charges are separated by 16 and feel a mutual repulsive force of 1.55. The charge of one is three times that of other.
Now a peg is placed 4/5 of the way down pendulum's path so that when the mass falls to its vertical position it hits and wraps around the peg. As it wraps around the peg and attains its maximum height it ends a distance of 3/5 L below its starting po..
How many wavelengths are contained in the light wave passing back and forth through the oil?
Indicate the negative x direction by including a negative sign in the answer, but omit a sign for the positive x direction.
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 5.45 m/s2. If the car's initial speed is 33 m/s, how long does it takes to stop and how far does it travel, starting ..
