Aremote-controlled car is moving in a vacant parking lot. the velocity of the car as a function of time is given by v =[5.00m/s−(0.0180m/s^3)t^2]i^ + [2.00m/s+(0.550m/s^2)t]j^. a) what is the magnitude of the velocity of the car at t = 7.93 s ? b) what is the direction (in degrees counterclockwise from +x-axis) of the velocity of the car at t = 7.93 s ? c) what is the magnitude of the acceleration of the car at t = 7.93 s ? d) what is the direction (in degrees counterclockwise from +x-axis) of the acceleration of the car at t = 7.93 s ?

(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.)
