1. What is the average velocity of an object that travels 30 km in 5 s? 2. How long would it take an object moving at 5 m/s to travel 60 m? 3. What is the acceleration of an object that goes from 3 m/s to 5 m/s in 8 s? 4. An object accelerates at 6 m/s2 for 4 s. If the object initially was moving at 6 m/s what is its final velocity? 5. What is the acceleration...
The acceleration of an object as a function of time is given by a(t) = (1, 69 m/s^3)t, where t is in seconds. If the object is at rest at time t = 0 s, what is the velocity of the object at time t = 5, 5 s? Answer with three significant digits.
A student measures the velocity of an object moving along a track. At time t = 0 s, the object is moving at a constant 4.0 m/s in the positive x-direction. At time t = 3.0 s, the object begins to slow, stops at t = 5.0 s, and then moves in the opposite direction. At t = 6.0 s, the object as reached a speed of -2.0 m/s. It moves at this speed until the student quits taking data...
An object traverses a pipe with a velocity that obeys the following dependence on time, ! v =αt 2 + βt , where the velocity is measured in m/s and the time, t, in seconds. α and β are constants, α = −5⋅107 ,β = 3⋅105 . The acceleration of the object just as it leaves the pipe is zero. (a) What are the units of the constants α and β? Rewrite the velocity expression using the values of these...
An object's velocity as a function of time is shown in the plot below. The object begins at position s = 10 m at t = 0 s. What is the object's total displacement at t = 7 s? What is the object's position at t = 7 s? What is the total distance the object Innis moved between t = 0 and t = 7 s. What is the acceleration of this object at t = 1, 3, 5...
20. Suppose an object moves so that its velocity at time t is described by the function v(t) = t2 – 8t + 7. Express the total distance traveled by the particle from time t=0 to 1= 4 using an integral or combination of integrals. Then evaluate the integral(s) to determine the solution. You are allowed to use the integration capabilities of a graphing calculator to evaluate the integral(s).
