I need help on question 5? Assessment 3, Version 2.8Grading: There are 52 points available, but the assessment is graded out of 50 points.Note: You may use g =that air friction is negligible and that any situations described take place on or near the surface of10 to make the calculations easier. Also note that you may assumeEarth, unless specified otherwise.1.An object is released from rest by someone standing on a bridge. The object fallswithout hitting anything for 2.1 s.(a) How fast will the object be going at the end of that 2.1 s interval?(b) How far will the object have fallen during that 2.1 s interval?gailisshorlogtic1) 012.A ball is tossed straight upward with a velocity of 13 m/s. How long does it takeor to reach the highest point in its path?3.A box that weighs 120 N sits motionless on a level table, and a 30 N cat is nappingon top of the box. There are three separate forces acting on the box. List these forces, statewhat other object is involved with each force, give the numerical value of each force and thedirection that it acts on the box. (One way to answer this question is to draw a free bodydiagram of the box with annotations showing all of the requested information.)A Honda Fit with a mass of 1000 kg collides with a Ford F150 (mass = 3000 kg).The collision lasts 0.8 s. (Although there are numbers given, these questions are conceptual.Give an answer in words and explain your reasoning.)(a) Which vehicle experiences the greater impact force during this collision?(b) Which vehicle experiences the greater acceleration during this collision?(c) Compare the change in momentum of each vehicle.5.The driver of a car (total mass=2200 kg) going 20 m/s brakes to a stop over a periodof 2.7 seconds, during which the car covers a distance of 27 m.(a) How much work is done by the brakes of the car?(b) What must the average braking force have been in this situation?6.A motor is used to pull a crate horizontally across the ground at a constant speedof 1.7 m/s using a tension (in the cable) of 120 N. The crate weighs 850 N.(a) What is the net force on the crate in this situation?(b) What must the force of friction and coefficient of friction be while the crate is moving inthis situation?(c) How much work does the motor do for every 10 meters the crate is moved?(d) What must the minimum power of the motor be to maintain this speed of 1.7 m/s?
