6) On Earth, a scale shows that "yo mama'weighs 6000 N. a) What is yo mama's mass? (612kg) b) What would the scale read on the moon (g=1.60m/s^2) ? (979N) 7) If you had an infinitely long bowling alley (the pins are __ somewhere...) with no friction and you rolled a bowling ball straight down the alley,what will the bowling ball's motion be like? 8) State the action-reaction pair of forces for the following situations. Also draw a free-body diagram for ONE of the objects in each situation, labeling all appropriate forces. Kicking a brick wall with your foot. b) Catching a baseball with your glove. c) Moe and Larry sharing a fist bump. 9) According to Newton's 3^rd law of motion actions have an equal and opposite reaction. Bob the linebacker, who has a mass of 70kg, sees a huge 120kg running back with the ball and tries to tackle him. Bob tackles him with a 500N force, then bounces off while the running back barely steps backwards after the hit. a) How much force does the 120kg running back exert back onto 70kg Bob? b) Why is it that Bob accelerates much more than the running back from the same collision?

Answer 1

### a) Yo Mama's mass:

### b) Yo Mama's weight on the moon:

### Bowling ball's motion: It will continue to move at a constant velocity.### Action-reaction pairs:- Kicking a brick wall: Action - Foot exerts force on wall; Reaction - Wall exerts force on foot.- Catching a baseball: Action - Glove exerts force on baseball; Reaction - Baseball exerts force on glove.- Fist bump: Action - Moe's fist exerts force on Larry's fist; Reaction - Larry's fist exerts force on Moe's fist.### Force exerted by running back:

### Explanation for different accelerations: Bob has a smaller mass, so he experiences a greater acceleration when the same force is applied.

Answer 2

## Step1: Calculate Yo Mama's Mass on Earth### Use the formula

where

is the force (weight),

is the mass, and

is the acceleration due to gravity. Rearrange to

. Given

and

, solve for

.## Step2: Calculate Yo Mama's Weight on the Moon### Use the same formula

but with the moon's gravity

. Given

, solve for

on the moon.## Step3: Describe Bowling Ball's Motion on a Frictionless Alley### According to Newton's First Law, an object in motion will stay in motion at a constant velocity unless acted upon by an external force. Since there is no friction, the bowling ball will continue to move at a constant velocity.## Step4: Identify Action-Reaction Pairs and Draw Free-Body Diagrams### For each situation, identify the action and reaction forces as per Newton's Third Law. Draw a free-body diagram for one object in each pair.## Step5: Calculate Force Exerted by Running Back### According to Newton's Third Law, the force exerted by the running back on Bob is equal in magnitude and opposite in direction to the force Bob exerts on the running back.## Step6: Explain Different Accelerations### Use Newton's Second Law

to explain why Bob accelerates more than the running back. Given the same force, the object with the smaller mass (Bob) will have a greater acceleration.
