									         2.4 Equations for Uniform Acceleration

Recall: acceleration is the rate of change of velocity




Recall from last week:




Recall from lab:
Summary: for accelerated motion




Ex. a car accelerates uniformly from rest to 100 km/h in 4.5
s.
a) calculate the acceleration in m/s2
b) how far does it travel in the 4.5 s?
ex. A cart is pushed up a ramp at 4.0 m/s. If the deceleration
is 2.0 m/s2,
a) how far up the ramp does it go before it starts moving
   down the ramp?
b) At what is it 2.5 m from the starting point?
