Help helphelp it is 90km per hr​

Explanation:

The equation for acceleration is

which is the final velocity minus the initial velocity divided by the time. I first need to put the units all in the same terms. We have the velocity given as km/hr, but the time is given in seconds and that's not gonna work. I will change the velocity to km/sec:

That's the value we will use for the final velocity of this car in the equation for acceleration:

The second part of this problem asks how far the car travels in this 10 seconds. We just determined that the car can travel .025 km in 1 second, so in 10 seconds the car travels 10(.025) = .25 km

newton's third law, for every action there is an equal and opposite reaction.
