4 A car is traveling at a constant velocity with magnitude At the instant that the car passes a motor cycle officer the motor cycle accelerates from rest with acceleration a Sketch an grap?
# A car is traveling at a constant velocity with magnitude . At the instant that the car passes a motor cycle officer, the motor cycle accelerates from rest with acceleration . # ## Sketch an graph of the motion of both objects. Show that when the motor cycle overtakes the car, the motorcycle has a speed twice that of the car, no matter what the value of . ## Let be the distance the motorcycle travels before catching up with the car. In terms of , how far has the motorcycle traveled when its velocity equals the velocity of the car?

What is the formula used to find distance?
The distance travelled by an object in a given time is given by:Distance = Speed * TimeAlternatively for an object that is accelerating:Distance = (Speed of object before acceleration is applied * Time) + (0.5 * Acceleration * Time squared)If the object is accelerating from speed zero, the first set of brackets is irrelevant.Also, if the object is falling to the ground, acceleration = 9.81

Is acceleration a scalar quantity or vector quantity?
Acceleration is both a scalar and a vector. Acceleration is a Quaternion quantity. For example in Gravitational force F=ma = XW= [d/dr, Del] [ -mu/r , cmV]: a= [d(-u/r)/dr - cDel.V, cdV/dr + Del (-u/r) + cDelxV] a= [v2/r -cv/r cos(RV), dV/dt + w2R + cv/r sin(RV) 1RxV] The terms before the comma ',' are scalar accelerations and the terms after the comma are vector accelerations. v2/r is the centripetal acceleration, center seeking); -cv/r cos(RV) is the centrifugal acceleration (center fleeing); dV/dt = - cV/r is the tangential vector accceleration; w2R is the radial vector acceleration; cv/r sin(RV) 1RxV is the Curl (circulation) acceleration.
