A semi truck accelerates at 0.85 m/s2 over a distance of 140 m and reaches a velocity of 32 m/s. What was the truck’s initial velocity?

 vf2 = vo2 + 2ad  

vo = 28.0 m/s

d = 140 m 

a = 0.85 m/s2

vf = 32 m/s

32^2 = vo^2 + 2(0.85)(140)      

1024 = vo^2 + 238 

 vo^2 = 786 

 vo = √786    =  28.0 m/s

A driver is stopped at a red light. When the light turns green, she accelerates at a rate of 2.2 m/s2 for 6.5 s. How fast is she driving at the end of the acceleration period?

vf = vo + at  

t = 6.5 s        a = 2.2 m/s2

vo = 0 m/s         vf = ? 

vf = vo + at = 0 + (2.2)(6.5) t

vf = 14.3 m/s

A roofer drops a tool off the side of a house. The tool takes 2.4 seconds to hit ​the ground.

​a. How tall is the house?

vo = 0 m/s, t = 2.4 s, a = 9.8 m/s2

 d = vot + ½ at2         = 

 d = 28.22 m/s
