Newton’s 2nd LawPhysics 211R: RecitationNewton’s 2nd LawNotes:- A maximum of three students will be allowed per group.o In the event that a group of four students must be formed, you need to check with yourTA before starting to work on the activity.- All the members of the group must participate in the activity. If a student is not participating (even when present) s/he may receive a score of zero in the activity.- Students arriving 10 minutes or more past start will not be admitted.- This activity must be returned at the end of the recitation period. All the students completing the activity must be present when handing this to the TA, otherwise that student may not get credit.o Writing the name of a person not present is not permissible and may result in a potential academic integrity violation being processed.- After you receive the graded report back, you should make a copy of the front page (this page) and keep it for you records. This will serve as evidence of your grade for this activity.- You are responsible for checking your grade (in the course website) and report any mistakes to your TA within two weeks after the activity.Date: ________________Enter your name as it appears in your PSU registration, no nicknames please.Section #: ________________Name: _______________________________________Name: _______________________________________Name: _______________________________________Score: _______Newton’s 2nd LawThe Porsche 996 can accelerate from 0 to 60 mph in 4.6 seconds. A fully loadedtractor trailer, however, will leisurely take as much as 1.5 minutes to undergo thesame change in speed. The weight of the Porsche is stated to be 2920 lbs.Assume that the loaded tractor trailer has a weight of 30,000 lbs. Using SI unitsfor mass, force, and acceleration, determine the force required on each to achievethese results.1. If the tires on the Porsche exerted the same force on the road as the tractor trailer in Q1, then how fast (in miles per hour) would the Porsche be traveling after 4.6 seconds (if it started from rest)?2. The following graph illustrates Momentum vs. Time for a bullet being shot. It can be seen from the graph that the bullet is in the barrel of the gun for the first 0.006 seconds. Estimate the net force exerted on the bullet during this time.3. The following graph illustrates the Thrust vs. Time for an Estes™ B6-4 model rocket engine. - Estimate the total impulse supplied by the engine.- Determine the average thrust force provided by the
