A car accelerates uniformly from 3.5 m/s to 12.5 m/s in 4.5 s. What is the magnitude of the acceleration?
a) 0.3 m/s²
b) 0.5 m/s²
c) 2.0 m/s²
d) 3.6 m/s²

c) 2.0 m/s^2.

Step-by-step explanation:

Acceleration = change of velocity / time

= (12.5 - 3.5)/4.5

= 9/4.5

= 2.0 m/s^2.

251=21+565

Step-by-step explanation:

To factor the difference of two perfect squares, remember this rule: if subtraction separates two squared terms, then the sum and the difference of the two square roots factor the binomial. For example: Example 1: Find the square roots of the two terms that are perfect squares.
