Anormal walking speed is around 2.0 m/s . how much time t does it take the box to reach this speed if it has the acceleration 5.54 m/s2 that you calculated above?

Free runners jump long distances and land on the ground or a wall. how do they apply newton’s second law to lessen the force of impact?

The ability to make things happen is also called a. heat b. force c. matter d. energy

An alpha particle with kinetic energy 12.5 mev makes a collision with lead nucleus, but it is not "aimed" at the center of the lead nucleus, and has an initial nonzero angular momentum (with respect to the stationary lead nucleus) of magnitude l = p0 b, where p0 is the magnitude of the initial momentum of the alpha particle and b=1.40×10−12 m. (assume that the lead nucleus remains stationary and that it may be treated as a point charge. the atomic number of lead is 82. the alpha particle is a helium nucleus, with atomic number 2.) what is the distance of closest approach?
