An Elevator Climbs from the Ground Floor with an Acceleration of 1.4m/s2. A 76kg Person is riding in the Elevator. Determine the Force of the Floor of the Elevator on the Person. Would the Person Feel Heavy or Light during this Period of Acceleration? Explain Why. BONUS: How long will it take the Elevator to Pass the 5th Floor? (Each Floor of the Building is 4m High)

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
