Question

**These seem like easy questions, but I want to make sure I'm correct!

A) You are driving at 10 m/s in a straight line on level ground and come to a stop in 5 seconds. What is your acceleration?

B) You are driving at 10 m/s in a straight line on level ground and come to a stop in 20 meters. What is your acceleration?

C) You are driving around a curve at 30 m/s on level ground. Could your acceleration be zero?

D) You toss a coin straight up in the air. What is its aceleration when it reaches half its maximum height?

E) True or False: When a car windshield collides with a bug, the force of the collision is greater on the bug than the windshield.

F) Your weight is the gravitational force with which the Earth attracts your body. On what object does the reaction to this force act?

G) When an Olympic ski jumper is in mid-air, neglecting air resistance, what is her acceleration?

H) On Earth a petite woman weighs 490 N. What is her mass on the moon, where the acceleration due to gravity is only 1.6 m/s2?

A. decceleration = -acceleration = 2m/s^2

B. decceleration = -acceleration = 2.5 m/s^2

C.Yes

D. -gravity

E.True

F. Body. point of contact . Normal

G Acceleration due to gravity

H mass = 490/9.8. = 50Kg

Weight on moon = m*g = 50*1.6 = 80N
