Can someone help me with these?
1. Which of the following properties of an object determines its terminal velocity when the object falls toward the Earth?
a. shape
b. weight
c. mass
d. density
2. A 1-kilogram mass is dropped from an altitude of 1,000 meters. If it accelerates at the rate of 10 m/s/s, how fast will it be moving in 5 seconds?
a. 10 m/s
b. 30 m/s
c. 50 m/s
d. 150 m/s
Thanks!

1) All of them. Your teacher probably wants an answer of "shape" but the other three are interrelated and also determine the terminal velocity. A ten inch bowling ball has a different terminal velicity than a ten inch plastic inflated ball.
2)c 50 m/s

The terminal velocity is dependent on the object's shape.
Using the basic kinematics equation (velocity final = velocity initial + acceleration * time) an object starting from rest would be traveling toward the ground at 50 m/s after 5 seconds. 0 + 10*5 = 50
