Jacob is driving a Ram Truck, while Andrew is driving a smart car. Both decided it was a great idea to drag race down the street. They noticed a cop at the end of the light so they slammed on breaks. Which driver will stop first, and why?
What is...Andrew due to his car having less mass which results in less force used to stop. In contrast since Jacob has a bigger vehicle he has more mass being harder to stop.

I have an object that has a mass of 50g and I apply a force of 30N to slide it across the table. What is the accelerating of the box once I slid it?
What is..
Asking for acceleration, they gave me f= 30N m=50g.
Formula is A=f/m A=0.6g
