WebHomework, Chapter 3: Linear Motion. ... Exercises (Discussion Questions) Ex 3.22 Suppose that a freely falling object were somehow equipped with a speedometer. By how much would its speed reading increase with each second of fall? Every second, its speed increases by 10 m/s. That means its acceleration is 10 (m/s)/s. WebProblem 2: Hans Full is pulling on a rope to drag his backpack to school across the ice. He pulls upwards and rightwards with a force of 22.9 Newtons at an angle of 35 degrees above the horizontal to drag his backpack a horizontal distance of 129 meters to the right. Determine the work (in Joules) done upon the backpack.

WebScalars and vectors are two kinds of quantities that are used in physics and math. Scalars are quantities that only have magnitude (or size), while vectors have both magnitude and direction. Explore some examples of scalars and vectors, including distance, displacement, speed, and velocity. Created by Sal Khan.

WebLinear Motion Speed refers to how fast an object is moving. It is a scalar. Avg speed in metres per second (m/s) = Distance covered Time Taken So, a 100m sprint run in 15s: Avg speed = 100 = 6.67 (m/s) 15 Velocity is a similar concept to speed but includes ‘direction’. It is defined as the rate at which an object changes its position. WebAverage speed = total distance ÷ total time = 1,700 m ÷ 50 s = 34 m/s. Look at this velocity-time graph and answer the question.
