64.An object is shot upwards, from the ground, with an initial velocity of 120 m/s. How high will it be after 4.0s? 65.An object is traveling with a constant velocity of 5 m/s. How far will it have gone after 7 s? 66.You are 12 miles north of your base camp when you begin walking north at a speed of 2 miles per hour. What is your location, relative to your base camp, after walking for 5 hours? 67.An object, initially at rest, moves 250 m in 17 s. What is its acceleration? 68.An object is shot upwards, from the ground, with an initial velocity of 40 m/s. How high will it be after 2.0s? 69.An object is dropped from a 42 m tall building. How long does it take to reach the ground? 70.An object is moving with an initial velocity of 23 m/s. It is then subject to a constant acceleration of 3.5 m/s2for 12 s. How far will it have traveled during the time of its acceleration? 71.An object is moving with a constant velocity of 278 m/s. How long will it take it to travel 7500 m? 72.An object travels at a constant velocity of 15 m/s for 5.0 seconds. How far does it move during that time? 73.How long will it take a person walking at 2.1 m/s to travel 13 m? 74.You are at a rest stop 250 miles north of New York City. You then travel north at a constant velocity of 65 miles per hour for 2.0 hours. Describe your location relative to New York City.
75.An object is at rest when it undergoes a constant acceleration of 13 m/s2for 5.0 seconds. How far will it have traveled during this time? 76.An object is dropped from the top of a building and strikes the ground 2.0s later. How tall is the building? 77.An object accelerates from rest with a constant acceleration of 7.5 m/s2. How fast will it be traveling after it goes 21 m? 78.An object experiences an acceleration of 9.8 m/s2over a distance of 210 m. After that acceleration it has a velocity of 380 m/s. What was its velocity before being accelerated? 79.An object accelerates from rest to a speed of 24 m/s over a distance of 56 m. What acceleration did it experience? 80.An object experiences an acceleration of 6.8 m/s2. As a result, it accelerates from rest to 24 m/s. How much distance did it travel during that acceleration? 81.A car which is traveling at a velocity of 15 m/s undergoes an acceleration of 6.5 m/s2over a distance of 340 m. How fast is it going after that acceleration? 82. A car slams on its brakes creating an acceleration of -3.2 m/s 2 . It comes to rest after traveling a distance of 210 m. What was its velocity before it began to accelerate? Homework
