How long does a car with an acceleration of 2.0m/s2 take to go from 10m/s?
a = 2 m/s^2 means that v grows by 2 m/s every second.
So, what do you think? v = at
To find out how long it takes for a car with an acceleration of 2.0 m/s^2 to go from 10 m/s to a certain speed, you can use the following formula:
v = u + at
Where:
v = final velocity
u = initial velocity
a = acceleration
t = time
In this case, the initial velocity (u) is 10 m/s, the acceleration (a) is 2.0 m/s^2, and we want to find the time (t). The final velocity (v) is not provided, so let's assume that the car reaches a velocity of v.
Rearranging the formula to solve for time (t), we get:
t = (v - u) / a
Substituting the values we have:
t = (v - 10) / 2.0
Without the final velocity (v), we cannot determine the exact time. If you have the final velocity, you can substitute it into the equation to calculate the time it takes for the car to reach that velocity.
