ANSWER:
a. Velocity decreased
STEP-BY-STEP EXPLANATION:
If the person inside the bus experiences a forward movement, this means that the bus is braking, since by action-reaction to compensate for the movement, the body moves forward.
When braking, it means that there is a decrease in speed, therefore, the correct answer is a. Velocity decreased
Answer:
Explanation:
We will use the equation F - f = ma, which is a fancy way of stating Newton's 2nd Law.
F = +50.0,
f = -30.0,
m = 7.60 kg. Therefore:
50.0 - 30.0 = 7.60a and
20.0 = 7.60a and
a = 20.0/7.60 so
a = 2.63 m/s/s to the right
Answer:
The mass will stay the same throughout time
