B. Draw your free-body diagram. Is there a net force on you?
C. Describe what happens to you as the car slowsdown?
D. Suppose now that the bench is not slippery. As the carslows down, you stay on the bench and dont slide off. What force is responsible for you deceleration?
E. In which directin does this froce point?

Answer 1

a. i. applied force

ii. gravitational force

iii. normal force of reaction
