1. A car maintains a constant velocity of 100 mi/hr for 2 minutes, what is its average acceleration? 2. What is the acceleration of a car that constantly increases its speed from 35 km/hr to 55 km/hr in 5
seconds?

An inclined plane wrapped around a metal shaft is a a. lever b. screw c. pulley d. wedge

The graph represents the distance a car travels over time while on the highway. which statement about the car's trip is accurate? a) the car does not move over time. b) the car travels at a constant velocity. c) the car's velocity increases constantly over time. d) the car's velocity decreases constantly over time.

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
