A car starts from rest and accelerates uniformly over a time of 5.21 seconds for a distance of 110 m. Determine the acceleration of the car.
d= v_i*t+1/2*a*t^2→110=0+.5a*27.14→.5a=4.05→a=8.1m/s^2
Upton Chuck is riding the Giant Drop at Great America. If Upton free falls for 2.6 seconds, what will be his final velocity and how far will he fall?
d= v_i*t+1/2*a*t^2→d=0+.5*-9.8*6.76→d=32.68m
d= v_i*t+1/2*a*t^2→110=0+.5a*27.14→.5a=4.05→a=8.1m/s^2

A race car accelerates
uniformly from 18.5 m/s to 46.1 m/s in 2.47 seconds. Determine the acceleration
of the car and the distance traveled.
v_f=v_i+a*t→46.1=18.5+a*2.47→a=11.17m/s^2
d=(v_i+v_f)/2*t→d=79.78m
