Question

A low rider truck accelerates from 0 m/s to 30.0 m/s with a displacement of 50m. What is the vehicle's acceleration?

a. 2.00m/s
b. 5.00m/s
c. 9.0m/s
d. 10.0m/s

Answer 1

a = 9 [m/s²]

Step-by-step explanation:

To solve this problem we must use the following equation of kinematics.

`v_(f)^(2)=v_(o)^(2) +2*a*x`

where:

Vf = final velocity = 30 [m/s]

Vo = initial velocity = 0

a = acceleration [m/s²]

x = displacement = 50 [m]

Now replacing:

`30^(2)=0 +2*a*50\\100*a=900\\a=9[m/s^(2) ]`
