Question

If Minnie the Mouse starts moving at 2m/s and increases her velocity to 4m/s because she is being chased, what is heracceleration if the time is 2 seconds?

Answer 1

1m/s²

Step-by-step explanation:

Given parameters:

Initial velocity = 2m/s

Final velocity = 4m/s

Time of chase = 2s

Unknown:

Acceleration = ?

Solution:

Acceleration is the rate of change of velocity with time;

A =
`(v - u )/(t)`

A is the acceleration

v is the final velocity

u is the initial velocity

t is the time taken

A =
`(4 - 2)/(2)` = 1m/s²
