2.
Can a car traveling on an interstate highway have a negative velocity and a positive acceleration at the same time?
a)
Yes, the car would be traveling in the negative direction and slowing down.
b)
Yes, the car would be traveling in reverse and slowing down.
c)
Yes, the car is traveling in the negative direction and speeding up.
d)
No, the car must have the same sign for both.
3.
Does a car that is slowing down always have a negative acceleration?
a)
Yes, a negative acceleration means to slow down always.
b)
No, it just means that the velocity is positive.
c)
No, it just means that the velocity is negative.
d)
Maybe.
