Question
Transcribed Image Text:A 1500 kg car was moving +31 "½ (E) in the
exit lane, but 7.0 s later only +10 m/ (E) at the
S
exit ramp.
b) compute the car's displacement (vector!) if its
acceleration was constant during that interval
O +217 m (E)
+70 m (E)
O +143.5 m (E)
O +290.5 m (W)
O +73.5 m (E)
O -73.5 m (W)
Expert Solution
Step 1
Given that
Initial velocity of the car u = +31 m/s along East
Final velocity of the car after t = 7.0 s is v = +10 m/s along East
Let the constant acceleration of the car is a .
