Homework Answers
Given : vf = 20.1 m/s , v0 = 0 m/s , t = 2 s
Solution :
(a) Acceleration
Using the equation of motion :
vf = vi + at
20.1 m/s = 0 + a(2s)
= 10.05 m/s2
Answer : 10.05 m/s2
(b) Distance travelled
Using equation of motion :
d = v0t + (1/2)at2
= (0)(2s) + (1/2)(10.05 m/s2)(2s)2
= 20.1 m
Answer : 20.1 m
