Question

An automobile with an initial speed of 6.7m/s accelerates uniformly at the rate of 5.00m/s^2. Find the final speed after 10.0 s.

Answer 1

Answer:

vf = 56.7 m/s

Explanation:

vi = 6.7 m/s

a = 5.00 m/s^2

t = 10 sec

vf = ?

a = (vf - vi )/t

5 = (vf - vi)/10

5 * 10 = vf - 6.7          

50 + 6.7 = vf

vf = 56.7 m/s
