How far (in m) will Object B have gone in 30.0 seconds if their acceleration is 20.0 m/s2?

Answer 1

Answer:

9000m

Explanation:

Given parameters:

Time  = 30s

Acceleration  = 20m/s²  

Unknown:

Distance traveled  = ?

Solution:

To solve this problem, we use one of the kinematics equation.

     S  = ut + $\frac{1}{2}$at²  

u is the initial velocity = 0m/s

t is the time taken

a is the acceleration

           S  = (0 x 30) + ( $\frac{1}{2}$ x 20 x 30² ) = 9000m
