Whats the equation?? I haven't done this is a while. Don't show me the answer i want to figure it out cus that's just how i roll thanks!
A car accelerates uniformly from 10 m/s to 20 m/s in 4.2 seconds. What is the magnitude of its acceleration?
Do i times everything together to find the magnitude??
a = (v-u)/t
v = final velocity (m/s)
u = initial velocity (m/s)
t = time taken for change in velocity (s)
a = acceleration (m/s^2)
your 20 m/s is your final velocity and 10 m/s is your initial velocity. that is over 4.2 seconds. then you would solve for acceleration

A car decelerates uniformly from 24 m/s to 18 m/s in 3.0 seconds. How far does it travel during this time?
To find the magnitude of acceleration, you need to use the equation for uniform acceleration:
a = (vf - vi) / t
In this equation:
a is the magnitude of acceleration,
vf is the final velocity,
vi is the initial velocity,
and t is the time taken.
In the problem given:
vf = 20 m/s (final velocity),
vi = 10 m/s (initial velocity),
and t = 4.2 seconds (time taken).
To find the magnitude of acceleration, substitute these values into the equation and perform the calculations.
a = (20 - 10) / 4.2
Now, all you need to do is calculate the value of (20 - 10) and divide it by 4.2 to find the magnitude of acceleration.
