Question

WILL GIVE BRAINLIEST!!!!!!!!!!!!!!!! WORTH 30 POINTS!!!!!!!!1 HELP!!!!! SHOW YOUR WORK!!!!!!!!!! Part II MATH: Newton’s 2nd Law states that force is affected by both mass and acceleration (F=ma). We also learned that objects fall on Earth at the same rate. This is the acceleration due to gravity (g = 9.8m/s2). Use this information to solve the following problems. Show your work! Include Units! Round answers to 2 decimal places.
9. What force is needed to make ball fall on Earth if it has a mass of 13kg?
Answer:


10. What is the mass of an object falling at the acceleration due to gravity with a force of 19N?
Answer:

11. A feather (mass = 0.1kg) and a bowling ball (4.5kg) will both fall at the SAME rate on Earth (g=9.8m/s2) if there is no air resistance. How much force is required to make each object fall?
Feather Answer:

Bowling Ball Answer:

Answer 1

(9)  The force needed to make the object fall on Earth is 127.4 N.

(10) The mass of the object falling at the acceleration due is 1.94 kg.

(11)  The force required for feather is 0.98 N and the force required for the bowling ball is 44.1 N

(9) The force needed to make the object fall on Earth is calculated form Newton's second law of motion.

F = mg

where;

• m is the mass of the object = 13 kg
• g is acceleration due to gravity  = 9.8 m/s²

F = 13 x 9.8 = 127.4 N

Thus, the force needed to make the object fall on Earth is 127.4 N.

(10) The mass of the object is calculated from Newton's second law of motion.

F = mg

$m = \frac{F}{g} \\\\m = \frac{19}{9.8} \\\\m = 1.94 \ kg$

Thus, the mass of the object falling at the acceleration due is 1.94 kg.

(11) The force required to make each of the objects fall is calculated from Newton's second law of motion.

Force required for feather: F = 0.1 x 9.8 = 0.98 N

Force required for the bowling ball: F = 4.5 x 9.8 = 44.1 N.
