Pleaseeeeee help with these two questions:
A car accelerates for 4.5 seconds at a rate of 2 m/s^2. If the car was driving at 10 m/s initially, what is it's final velocity? The car is moving on a straight path.
12.25 m/s
22.5 m/s
4.44 m/s
19 m/s

QUESTION 2
If a 5000 kg car hits a 500 kg motorcycle, which of the following is true? Assume they collide and cleanly bounce off of each other.
-The motorcycle will have a greater acceleration after the collision due to the greater force exerted by the car on
impact.

-The forces are equal and opposite so both vehicles will have the same acceleration after the impact.

-The motorcycle will have a greater acceleration after the collision due to its lower inertia.
