If a ball is thrown into the air with a velocity of 100 ft/s, its height in feet after t seconds is given by LaTeX: h\left(t\right)=100t-16t^2h ( t ) = 100 t − 16 t 2 . Find the average velocity of the ball for the time period from t = 1 to t = 3.

In a series circuit the __ is the same at every point

You want to move a heavy box with mass 30.0 kg across a carpeted floor. you pull hard on one of the edges of the box at an angle 30∘ above the horizontal with a force of magnitude 240 n, causing the box to move horizontally. the force of friction between the moving box and the floor has magnitude 41.5 n . what is the box's acceleration just after it begins to move

Scientists studying an anomalous magnetic field find that it is inducing a circular electric field in a plane perpendicular to the magnetic field. the electric field strength 1.5 m from the center of the circle is 6.5 mv/m.
