Question

1. A truck speeds up from a velocity of 6 m/s to 14 m/s in 4 seconds. What is the truck’s acceleration?

Answer 1

help

Answer 2

\[a = \frac{ v_{f} - v_{i} }{ time }\]

Answer 3

Acceleration is equal to the final velocity minus the intial velocity, which is then divided by the changw in time.

Answer 4

wait im confused

Answer 5

Say a car starts with 2m/s and ends with 4m/s over 5 seconds

\[Acceleration = \frac{ 4- 2}{ 5}\]

Answer 6

so 2/5 and then 0.4

Answer 7

Correct. Do you see how to do your problem now?

Answer 8

(Final Velocity - Initial Velocity/(Time)

Answer 9

yes sir i do

Answer 10

can you help with a couple more problems i dont understand

Answer 11

sure
