Question

A race starts from rest and accelerates down a track at a rate of 3.0 m/s square (2) for 10 seconds, what is the cars final velocity?

Answer 1

To find the car's final velocity, use the equation v = u + at. Plugging in the given values, we find that the final velocity is 30.0 m/s.

Step-by-step explanation:

To find the final velocity of the car, we can use the equation:

v = u + at

Where:

• v is the final velocity
• u is the initial velocity (0 m/s, as the car starts from rest)
• a is the acceleration (3.0 m/s²)
• t is the time (10 seconds)

Plugging in the values, we get:

v = 0 + (3.0)(10)

v = 30.0 m/s

Therefore, the car's final velocity is 30.0 m/s.

Answer 2

Answer:30m/s

Step-by-step explanation:

acceleration=(final velocity-initial velocity)/time taken

so 3=(x-0)/10

so x-0=30

so x=30

so the final velocity is 30m/s
