Basketball Physics Question
A basketball player releases his foul shot with an initial speed of 23.5 ft/sec. What value(s) of the initial angle θ will cause the ball to pass through the center of the rim? Neglect any clearance considerations as ball goes through rim.
A charge 4.97 nC is placed at the origin of an xy-coordinate system, and a charge -2.04 nC is placed on the positive x-axis at x = 4 cm. Find the direction of the total force acting on the third charge
When cars are equipped with flexible bumpers, they will bounce off each other during low-speed collisions, thus causing less damage. Find the speed of the lighter car just after the collision
A force of k is applied to an object for a small fraction of a second, t_k, less than the duration of one frame, t_f. Our simulation doesn't support applying forces for less than an entire frame, so if we wanted to simulate the effect of force k over..
A 45.0 g ball of copper has a net charge of 1.75 µC. What fraction of the copper's electrons have been removed
A circular wire loop of wire has radius 2.3cm and resistance 0.045ohm. A magnetic field is perpendicular to the loop, At what rate must the field change in order to induce a current of 1.1ma in the loop
