All the tools & learning materials you need for study success - in one app.
Get started for freeIn the given figure what kind of motion is represented by the situation with K + U = A? B? C?Think about the range of rin each situation, For example, Crepresents a circular orbit (constant r).
A constant force acts through a displacement. How much work does this force do?
A nucleus whose mass is undergoes spontaneous alpha decay. The original nucleus disappears and there appear two new particles: a He-4 nucleus of mass (an alpha particle consisting of two protons and two neutrons) and a new nucleus of mass . (Note that the new nucleus has less mass than the original nucleus, and it has two fewer protons and two fewer neutrons.)
(a) What is the total kinetic energy of the alpha particle and the new nucleus?
(b) Use the conservation of momentum in order to determine the kinetic energy of the alpha particle and kinetic energy of the new nucleus.
Jack & Jill are maneuvering a boat near a dock. Initially the boat’s position is and its speed is 1.3m/s . As the boat moves to position (4,0,2). Jack exerts a force (-400, 0, 200) N and Jill exert a force and Jill exert a force (150,0,300)N . (a) How much work does jack do? (b) How much work does Jill do? (c) Without doing any calculations, say what is the angle between the (vector) force that Jill exert, and the (vector) velocity of the boat. Explain briefly how you know this (d) Assuming that we can neglect the work done by the water on the boat, what is the final speed of the boat?
A particle moves inside a circular glass tube under the influence of a tangential force of constant magnitude F (Figure 6.78). Explain why we cannot associate a potential energy with this force. How is this situation different from the case of a block on the end of a string, which is swung in a circle?
