Hi there hope you are well .I will need all questions to be done, and also I will need this in 2.5 hours. I know its long but I hope u understand. Thanks

5:03 TEMU QO But ill 69% PHYSICS 30 UNIT... Q . . . PHYSICS 30 UNIT EXAM #2: NEWTON'S LAWS A: True/False - read each statement carefully. Clearly write T or F in the blank. Inertia is the tendency of all objects to resist motion and ultimately stop. 2. Fast-moving objects have more inertia than slow-moving objects. 3. The mass of an object is dependent upon the value of the acceleration of gravity. if all other variables are equal, then an object with a greater mass would have a more 4. difficult time accelerating. 5. An object can experience two or more forces and not accelerate. An object's weight can be measured in kilograms or Newtons depending upon the system of 6. measurement. 7. If an object is moving to the right, then there must be a rightward force acting on it. It is possible to have an odd number of forces (3 or 5 or 7 forces) acting on an object and 8. STILL have a balanced net force (ie net force = zero) The net force required to keep a 1.00 kg rock moving at 2.0 m/s is 0 Newtons. According to Newton's Third Law, Action-Reaction forces are equal and therefore cancel 10. each other out. Pg- B: Short Answer - Read the question carefully and make sure answers are complete, may use point form 1. The stronger, heavier team in a tug-of-war does not create a larger tension in the rope than the weaker, lighter team. Although all of Newton's Laws can play a role in any situation, one of Newton's Laws of Motion BEST explains how this happens. Which law and why? (2 marks) 2 . jerk a paper towel from a roll to t stead of pulling it smoothly. Although New Laws can play a role in any situation Newton's Laws of Motion BEST exp this. Which law and why?

You usually jerk a paper towel from a roll to tear it instead of pulling it smoothly. Although all of Newton's Laws can play a role in any situation, one of Newton's Laws of Motion BEST explains this. Which law and why? (2 marks) 3.

Michelle is pulling a 2.8 kg toy along the flat sidewalk. The string she is hanging onto is horizontal. Knowing that Us = 0.656 and Hx = 0.343 (4 marks) a. Determine the minimum force required in the string to initiate movement of the toy. If Michelle is pulling the toy horizontally along the sidewalk, with a force of 10.0 N, what is the acceleration of the toy? pg- 3 3. Billy jumps out of the plane and his 79.0 kg body creates a drag force of 413 N at exactly 3.00 s after jumping. Billie has a drag coefficient of 1.20, his cross sectional area is 0.900 m and the air density is 1.15 kg/m3. (6 marks) a. What is his acceleration at exactly 3.00 s after he jumps out of the plane? b. What is Billie's terminal velocity?PB- 3 3.
