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. Choose the appropriate equation.
v=vo+at
d=vot+1/2at2
v2=vo2+2ad
d=1/2(v+vo)t

A mass of 5 kg slides across a frictionless table with an initial velocity of 10 m/s. The wind starts to blow in the direction the mass is moving causing it to accelerate at a constant rate. After 2 seconds, the mass is moving at a velocity of 15 m/s. What is the acceleration of the mass?
12.5 m/s2
7.5 m/s2
5.0 m/s2
2.5 m/s2
