The kinematic equations can describe phenomena other thanmotion through space and time. Suppose x represents a person’sbank account balance. The units of x would be dollars($), and velocity v would give the rate at which the balancechanges (in units of, for example, $/month). Accelerationwould give the rate at which v changes. Suppose a personbegins with ten thousand dollars in the bank. Initial moneymanagement leads to no net change in the account balance sothat v0 =0. Unfortunately, management worsens over time sothat a = -2.5 x 102 $/month2. Assuming a is constant, findthe amount of time in months until the bank account is empty.
Wellington Wildcat is rushing to get to a parade in time to be the grand marshal. He’s standing in theback of a flatbed truck while McFogg the Dog races at 25 m/s towards town. Suddenly, McFogg sees atiny maple leaf in the road 55 m ahead, and, being a proud Canadian, slams on the brakes to protect thesacred totem. Since McFogg is known to ride the brakes like a real jerk, let’s assume his reaction time tohit the breaks is essentially zero.A. Can McFogg actually stop before the truck reaches the leaf? The coefficients of friction betweenrubber tires and dry concrete are: μs = 1.00, μk = 0.80. When answering this question, be sure toinclude a free-body diagram representing the truck and its stellar mascots as a single object.B. Now here’s the real serious question: Is it possible for McFogg to stop short of the leaf such thatWellington does not slip and slide into the back of the truck cab? The coefficients of friction forWellington’s shoes on the bed of the truck are: μs = 0.60, μk =…

Dr. John Paul Stapp was U.S. Air Force officer who studiedthe effects of extreme deceleration on the human body. OnDecember 10, 1954, Stapp rode a rocket sled, acceleratingfrom rest to a top speed of 282 m/s (1015 km/h) in 5.00 s, andwas brought jarringly back to rest in only 1.40 s! Calculate his(a) acceleration and (b) deceleration. Express each inmultiples of g (9.80 m/s2) by taking its ratio to theacceleration of gravity.
You can accelerate and brake on your bicycle with a maximum magnitudeof the acceleration of 3 (m/s)/s. Your top speed is 12 m/s. You want to drop ofyour physics textbook at your friend who normally works with an electronictextbook version, but just called and asked you for your printed copy for theafternoon. She lives 168m up the road from you. You need 11 seconds to runout of your apartment and grab your bike, and you need another 11s to run toyour friend’s apartment door to hand her the book after stopping with your bike.How long to you need in total to bring her the book?
A 50.0-g Super Ball traveling at 29.5 m/s bounces off a brick wall and rebounds at 16.0 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 3.30 ms, what is the magnitude of the average acceleration of the ball during this time interval? Can you please show all the steps whem answering
Pedro who is on top of a roof of a high building drops a piece of metallic material. A second piece of metallic material is dropped 2.0 seconds later.

The acceleration of a particle is given by a - 2t - 17, where a is in meters per second squared and tis in seconds. Determine the velocity and displacement as functions of time. The initial displacement at t= 0 is so = -2 m, and the initial velocity is vo = 4 m/s. Once you have determined the functions of time, answer the questions. Questions: When t = 5.9 s, m i m/s m/s?
A student begins at rest and then walks north at a speed of v1=0.65m/s. The student then turns south and walks at a speed of v2=0.28m/s. Take north to be the positive direction. a)What is the student's overall average velocity vavg, in meters per second, for the full trip assuming the student spent equal times at speeds v1 and v2? b) If the student travels in the stated directions for 30.0s30.0s at speed v1 and 20.0s at speed v2, what is the net displacement, in meters, during the trip? c) If it takes the student 1.2s to reach the speed v1, from rest, what is the magnitude, in meters per squared second, of the student’s average acceleration during that time?
