By how much does the speed of a vehicle moving in a straight line change each second when it is accelerating at 4 m/s2?
By how much does the speed of a vehicle moving in a straight line path would change each second when it is accelerating at 2km /h's at 4 km/h's
To determine how much the speed of a vehicle changes each second while accelerating at 4 m/s^2, you can use the equation for acceleration:
acceleration (a) = change in velocity (Δv) / change in time (Δt)
Here, we are given the acceleration, which is 4 m/s^2. We need to find the change in velocity per unit time, which corresponds to the change in speed.
Since acceleration is the rate of change of velocity, the change in velocity (Δv) per unit time (Δt) is equal to the constant acceleration:
Δv / Δt = a
Rearranging the equation, we can solve for the change in velocity per unit time:
Δv = a * Δt
Given that the time interval (Δt) is 1 second, we can substitute the values:
Δv = 4 m/s^2 * 1 s
Therefore, the change in velocity (or speed) per second is 4 m/s.
