A car speeds up form 0m/s to 4m/s in 10 seconds. What is the acceleration?
Look up the formula for acceleration, and then this is simple plug-n-chug.
Use (v_final - v_initial)/time = average acceleration.
Here v_final=4m/s, v_initial=0m/s and t=10.
To find the acceleration, we can use the formula:
Acceleration = (v_final - v_initial) / time
In this case, the final velocity (v_final) is 4 m/s, the initial velocity (v_initial) is 0 m/s, and the time (t) is 10 seconds.
So, plugging in the values into the formula:
Acceleration = (4 m/s - 0 m/s) / 10 s
Simplifying this gives:
Acceleration = 4 m/s / 10 s
Calculating this division:
Acceleration = 0.4 m/s²
Therefore, the acceleration of the car is 0.4 m/s².
