A test vehicle on a track goes through photo gates spaced 25 m apart at the following times: 2.00 sec, 3.30 sec, 4.30 sec
a) Plot the position versus time of the vehicle.
b) Plot the average speed of the vehicle in the time intervals versus time.
Next Q) A rally driver has to maintain a constant speed between checkpoints. She arrives at these points at the following times
26 mi at 31 min 12 sec
48 mi at 57 min 24 sec
87 mi at 1 hr 43 min 15 sec
105 mi at 2 hr 8 min and 49 sec
a) What is the most probable (i.e. average) speed that she is trying to maintain?
b) What is her largest deviation from this average speed?
This is the hard one) What is the acceleration of a vehicle that charges its velocity from 100 km/h to a dead stop in 10 s?

Glad to hear the 1st ones are easy.
This is the hard one)
Use
Vf = Vo + a*t
Acceleration is sometimes given in km/hr/s. If you don't think you're allowed to do it that way, convert units first.
