The speed of a car traveling on a straight road increases from 63 m/s to 75 m/s in 4.2 s what is the cars acceleration ?
Please help
..... and it is Physics :)
I am not a mind reader.
acceleration = rate of change of velocity or the slope of the velocity curve
a = (V2-V1)/ (T2-T1)
here:
a = (75 - 63) / (4.2 - 0)
a = (12 / 4.2) meters/ second^2
I am good at science but not math mixed with science. lol.
To find the car's acceleration, we can use the formula:
acceleration (a) = (final velocity - initial velocity) / time
Given:
Initial velocity (u) = 63 m/s
Final velocity (v) = 75 m/s
Time (t) = 4.2 seconds
Now, plug these values into the formula:
a = (v - u) / t
= (75 m/s - 63 m/s) / 4.2 s
= 12 m/s / 4.2 s
= 2.857 m/s²
Therefore, the car's acceleration is 2.857 m/s².
