A man is in a 1500kg car traveling at 60km/h (mind the units). a) What is the kinetic energy of the car? When the man presses the gas pedal the cars engine exerts a force given by F = FO - Ax^1/3 where FO and A are constants (FO = 1500N and A = 500N/m^1/3) and x is the distance travelled after the gas pedal is pressed. b)

units). a) What is the kinetic energy of the car? When
the man presses the gas pedal the cars engine exerts a
force given by F = FO-Ax^1/3 where FO and A are
constants (FO = 1500N and A = 500N/m^1/3) and x is
the distance travelled after the gas pedal is pressed. b)
Using the above equation find an expression for the
work done by the engine when the gas pedal is
pressed. c) The man holds the pedal down for 50m how
fast is the car be travelling? The car comes to an incline
of 6 degrees and the man doesn't use the brake or the
gas pedal. d) How far along the slope does the car go
before it stops.
