a stationary car with a mass of 1500 kg reaches a velocity of 15 m/s 5 seconds after starting, what is the car's acceleration
You don't need to know the mass to answer this.
Accleration is velocity change divided by time.
3 m/sec?
To calculate the car's acceleration, we can use the formula:
acceleration = change in velocity / time
In this case, the change in velocity is given as 15 m/s (final velocity) minus 0 m/s (initial velocity). The time is given as 5 seconds.
So, the acceleration can be calculated as follows:
acceleration = (15 m/s - 0 m/s) / 5 s
acceleration = 15 m/s / 5 s
acceleration = 3 m/s²
Therefore, the car's acceleration is 3 m/s².
