The change in velocity of a car can be calculated using the formula:
Δv=a⋅ΔtDelta v = a cdot Delta tΔv=a⋅Δt
Where:
- ΔvDelta vΔv represents the change in velocity
- aaa is the acceleration
- ΔtDelta tΔt is the change in time
In this case, the car has an acceleration of 1 m/s², and the change in time is 3 seconds. Plugging these values into the formula, we can calculate the change in velocity:
Δv=1 m/s²⋅3 s=3 m/sDelta v = 1 , ext{m/s²} cdot 3 , ext{s} = 3 , ext{m/s}Δv=1m/s²⋅3s=3m/s
Therefore, the change in velocity of the car after 3 seconds is 3 m/s.
