Due Date/Time: 10:35 AM Wednesday February 5, 2025.  Maximum Time Limit = 65 Minutes (in one sitting).  Must be taken in one 65-minute sitting/session.  IF YOU NEED TO USE SCRAP PAPER, ASK FOR SOME.   Be sure that you type all your answers and any work into the exam, too, please.   IF YOU NEED TO USE A CALCULATOR, IT MUST BE A REGULAR CALCULATOR (HAND-HELD).  PHONES AREN’T PERMITTED.   REMINDERS: Exams, tests, and quizzes are closed books, closed notes, closed slides, closed assignments, and taken individually.  No additional devices allowed other than the one (1) being used for the exam/test/quiz. Only the test/exam/quiz screen should be open.  A simple, basic calculator can be used (not phones).  No other windows, websites, programs are permitted. 

An object of 5 kg is moving initially at 4 m/s in the positive x direction. At time t=0, it is acted upon by a force F=(4t+1) N in the positive x direction. What is the velocity of the object at t=5 s?

A body is moving in the positive x direction while being acted upon by a net force. The graph of the net force as a function of the body’s position is represented in the figure below. When the body is at x=0, its speed is 20 m/s. At which of the marked points is the speed of the body the closest to 20 m/s?

One end of a string is tied to a wall, with a length L = 1.1 m from the wall to the point where the string touches a pulley. The other end passes over the frictionless pulley and is connected to a block of mass m = 0.35 kg. When the string is stretched over the pulley, its linear mass density is 4.40 × 10-4 kg/m. What is the wavelength of the third mode of standing wave on this string?

A body of mass m is sliding down an incline of 36 degrees with the horizontal (angle theta in the Figure below) at a constant speed v0{“version”:”1.1″,”math”:”v0″}. Find the coefficient of kinetic friction between the body and the surface of the incline.

A wheel is pivoted at its center. It has a radius R and mass M. A piece of clay of mass m and speed v is about to strike it at the bottom edge, tangentially, as shown, and sticks to it. What is the angular velocity of the system right after the collision?                                                      

A mass of 0.5 kg is oscillating on an ideal spring in simple harmonic motion with position as a function of time given by x ( t ) = ( 7.0  cm ) cos ⁡ ( ( 1.5  rad/s ) t + π 3 ) {“version”:”1.1″,”math”:”x(t)=(7.0\mbox{ cm}) \cos ( (1.5 \mbox{ rad/s} )t +\frac{\pi}{3})”} What is the spring constant of a spring?

A simple pendulum named Bob has a period of small oscillations T=1 s on Earth (assume g=9.80 ms2{“version”:”1.1″,”math”:”ms2″} ).  Bob is flown to a planet X and it is found that now its’ period of small oscillations is 2 s. What is the value of specific gravity on the planet X in  m / s 2 {“version”:”1.1″,”math”:”\mbox{m}/s^2″}?
