The time it takes the truck to change velocity is 2.67s.
What is time?
Time is the apparent progression of events from past to future
To calculate the time it takes the truck to change velocity, we use the formula below.
Formula:
- t = (v-u)/a................ Equation 1
Where:
- t = Time
- v = Final velocity
- u = Initial velocity
- a = accceleration
From the question,
Given:
- v = 25 m/s
- u = 15 m/s
- a = 3.75 m/s²
Substitute these values into equation 1
- t = (25-15)/3.75
- t = 10/3.75
- t = 2.67s
Hence, the time it takes the truck to change velocity is 2.67s.
