A proton and an electron are released from rest at the same time from the midpoint between two charged parallel plates. The plates are charged with equal surface charge densities of opposite signs. Ignore the interaction between the electron and the proton and consider only the interaction of each charge with the electric field of the plates. After being released, the proton will accelerate toward the negative plate, and the electron will accelerate toward the positive plate. (a) Which charge...

Two identical objects start at the same height above level ground. Simultaneously, object A is dropped and object B is launched horizontally with a speed of 20 m/s. Assume that air resistance is negligible. a) Which object hits the ground first, or do they hit the ground at the same time? b) Which object hits the ground with the greatest speed, or do they hit the ground with the same speed? c) If the two objects started at a height...
Two stones are relensed from rest at the same height, one after the other, so that they fall along the me vertical line. During the time that they are free falling (ignore air resistance) which of the following three statements is true? As time passes, the distance between the two stones: A. increases B. decreases C. stays the same Two stones are released from rest at the same height, one after the other, so that they fall along the same...
one-dimensional movement exercise: Two balls are dropped in a vacuum from the same height, but at different times; The second ball hits the ground 1.35 seconds after the first hits the ground. A. from the above information, deduce an expression that allows you to find the difference between your heights (∆h = h2-h1)
A ball is dropped from a height 24 m above the ground at t=0.0. Each time it bounces from the ground, its rebound speed is 60% of its impact speed. At the instant the first ball hits the ground, a second ball is released from the same place. Take g = 9.8 m/s2. At what height above the ground will they collide? (Take the ground as y=0.0 m)

Two protons are released from rest at time t = 0 at an original separation of L. Assume no other forces are relevant for this problem. a) Write a function relating the protons’ separation L to time with all units in mks. Since it is very hard to write this as separation L as a function of time t, instead write time t as a function of separation L.

The drivers of two cars having equal speeds hit their brakes at the same time, but car A has three times the acceleration as car B. If car A travels a distance D before stopping, how far (in terms of D) will car B go before stopping? If car B stops in time T, how long (in terms of T) will it take for car A to stop?
