Check Your Understanding How does your weight at the top of a tall building compare with that on the first floor? Do you think engineers need to take into account the change in the value of g when designing structural support for a very tall building?
(c) A claw hammer can be used both to drive nails into a piece of wood and to get themback out (see figure 1b). The person in the image needs to exert a force of 50 Non the hammer to pull the nail loose. The handle is 25 cm long, and the distancebetween the handle and the head of the nail is 2.0 cm. Find the force the hammeris exerting on the wood (not the nail!). You may assume that the point where thehammer touches the wood is along the line of the handle. Hint: Start your answerwith a free-body diagram. May I have a detailed step by step explanation of this c) problem? Its for a hand in homework and I don't know how to solve it

As a fish jumps vertically out of the water, assume thatonly two significant forces act on it: an upward force F exertedby the tail fin and the downward force due to gravity. A recordChinook salmon has a length of 1.50 m and a mass of 61.0 kg.If this fish is moving upward at 3.00 m/s as its head first breaksthe surface and has an upward speed of 6.00 m/s after twothirdsof its length has left the surface, assume constant accelerationand determine (a) the salmon’s acceleration and (b)the magnitude of the force F during this interval.
A nucleus that captures a stray neutron must bring the neutronto a stop within the diameter of the nucleus by means of thestrong force. That force, which “glues” the nucleus together, is approximatelyzero outside the nucleus. Suppose that a stray neutronwith an initial speed of 1.4 * 107 m/s is just barely captured by anucleus with diameter d = 1.0 * 10-14 m. Assuming the strongforce on the neutron is constant, find the magnitude of that force.The neutron’s mass is 1.67 * 10-27 kg.

The FedEx and UPS boxes have almost reached the top of the inclined plane they have been moving along and are now arrangedThe UPS box has a mass of 3.0 kg, and the FedEx box has a mass of 1.0 kg. The inclined plane is frictionless;however, the horizontal floor has coefficients of static and kinetic friction of 0.5 and 0.2. The pulley is frictionless, and the massesof the pulley and cord are negligible. Answer the following about this system. a.What is the size of the normal force on the UPS box?b. This system will begin to move if released from rest. However, if youpressed with a downward force on the FedEx box, this system could remain at rest.What size force is required? Your solution should include two free-body diagrams.c. If the system was set into motion down the ramp, without the forcementioned in the previous part, what would be the acceleration of the system? Yoursolution should include two free-body diagrams.
