vs. (20 pts) A bullet is fired horizontally underwater and experiences a strange viscous force given...
The toy gun in the figure below consists of a spring with spring constant k. It is loaded with a projectile of mass m and the spring is compressed a distance d. The toy gun is fired horizontally and the bullet travels a total distance L within the toy gun before it is released. A) Neglecting all resistive forces, determine the speed of the projectile vo once it exits the toy gun (i.e., express Vo in terms of the known quantities...
Total: 20 pts) A car is braking hard. There are two significant resistive forces acting on it, a quadratic (cv2) air drag, and a constant (umg) frictional force. If you are interested in finding v(x) (rather than v(t)), there is a commonly used method known as the "v dv/dx rule”, which uses the chain rule to rewrite ü = = di = v . a) [12 pts) Write down the equation of motion for Ü = (v) and use the...
