In a grocery store, you push a 14.5 kg shopping cart with a force of 12 N. If the cart starts from rest, how far does it move in 3 sec?

F=6kt This force acts on a particle of mass "m" that moves along a line. If the particle starts from rest, determine its velocity and position at time t.

a car depreciates in by avalue of $1000 per year. The original value of the car is $30,000. Let V(x) be the value of the car in x years. Write the linear function that represent the value of the car in x years. what will be the value of the car after 7 years?
