A car accelerates northwest from 35 to 62 m/s in a time of 14 seconds. What is the acceleration?
a = Vf - Vi / t
A) 27 m/s2 northwest
B) 1.9 m/s2 northwest
C) -1.9 m/s2 northwest
D) 61 m/s


Sagot :

Answer:

B) 1.9 m/s2 northwest

Explanation:

Given parameters:

Initial velocity  = vi  = 35m/s

Final velocity  = vf  = 62m/s

Time  = 14s

Unknown:

Acceleration  = ?

Solution:

Acceleration is the rate of change of velocity with time.

   Acceleration  = [tex]\frac{Vf - Vi}{t}[/tex]  

Vf is the final velocity

Vi is the initial velocity

t is the time taken

   Acceleration  = [tex]\frac{62 - 35}{14}[/tex]   = 1.93m/s² northwest
