Spanish:
Se tira una bola verticalmente hacia arriba, la magnitud de la aceleración de la bola, en

cada uno de los siguientes instantes es mayor que g, de la misma magnitud que g, menor

que g ó cero? EXPLIQUE.

a) Justo después de salir de sus manos

b) En su altura máxima

c) Antes de tocar al suelo.

English:
A ball is thrown vertically upwards, the magnitude of the acceleration of the ball, in each of the following instants is greater than g, of the same magnitude as g, less what g or zero? EXPLAIN.
a) Just after getting out of your hands
b) At its maximum height
c) Before touching the ground.

Jason and mia are both running in a race. as they approach the finish line, you being the physicist that you are decide to time how long it takes them to reach the end of the race. when you start your stop watch (you can take this as time t = 0 s) you notice that mia is an unknown distance d ahead of jason and both are moving with the same initial velocity v_0. you also notice that jason is accelerating at a constant rate of a_j, while mia is deaccelerating at a constant rate of -a_m. jason and mia meet each other for the first time at time t = t_1. at this time (t = t_1) jason's velocity is two times that of mia's velocity, meaning v_j (t_1) = 2v_m (t_1). a) draw the position vs. time graph describing mia's and jason's motion from time t = 0 to time t = t_1. clearly label your axes and initial conditions on your graph. b) draw the velocity vs. time graph describing mia and jason's motion from time t = 0s to time t = t_1. clearly label your axes and initial conditions on your graph. c) how long from when the stop watch was started at t = 0s did it take mia and jason to meet? express your answer in terms of know quantities v_0, a_m, and a_j. d) when the stop watch started at time t = 0s, how far apart, d, were mia and jason? express your answer in terms of know quantities v_0, a_m, and a_j.

Ametal ball with a mass of 0.028 kg is dropped from rest at a height of 1.0 meters above the ground. assuming the energy in the ball is conserved, how much kinetic energy will the ball have when it is 0.5 meters above the ground?

Which of the following is not an appropriate unit for acceleration? (kg/12 mihr? m/min/sec cm/30c?
