Acar is moving on a straight road in a fixed direction at a constant speed of v = 62 km/h with respect to the road. you wish to state the kinematic vectors of the motion of the car by using a cartesian coordinate system whose positive x-axis is pointed in the direction of the motion of the car and the origin is fixed at some point on the road. a. what is the expression for the velocity of the car, using the speed v and the unit vectors i, j, and k?
b. what is the x-component of the position vector, in units of kilometers, at time t=0.015 hr?
