11. If a cart has a mass of 20 Kg and is being pushed with a net force of 100 N, what will the acceleration of the cart be?

12. For the same mass cart as in Question 10, how much net force would be required
to cause it to accelerate at a rate of 8 m/s??

13.. If some items were removed from the cart and it now accelerates at a rate of
10m/s2 with a net force of 100 N acting on it, what is the new mass of the cart?

CAN SOMEBODY PLEASE HELP ME ANSWER THESE FOR MY TEST?! WILL GIVE BRAINLIEST.
