Question

A cart rolling down an incline for 5.0 seconds has an acceleration of 4.0 m/s2. If the cart has a beginning speed of 2.0 m/s, what is its final speed?

Answer 1

22m/s

Step-by-step explanation:

Given parameters:

Time = 5s

Acceleration = 4m/s²

Initial velocity = 2m/s

Unknown

Final speed = ?

Solution:

To solve this problem, we use the expression below;

v = u + at

v is the final speed

u is the initial speed

a is the acceleration

t is the time taken

So, insert the parameters and solve;

v = 2 + 4 x 5 = 22m/s
