1.  A bus is making a trip from Bigtown to Megacity. The average round trip speed is always58MPH on this journey. The round trip distance is120miles. At Megacity the bus waits exactly29minutes and then returns to Bigtown. If the bus has completed5/6of this entire journey, how long has it been since it left Bigtown on the way to Megacity? Round your answer to the nearest minute.

2.  The potential energy (J) [= Mass(kg) x Distance(m) x Acceleration of Gravity(m/s2)] of an object on earth depends on its distance from the ground. If you hold a hammer (mass =1 1/4kg)100cm from the ground, what is its potential energy? The acceleration of gravity is9.8m/s2. Hint: The unit for distance must be in meters when calculating potential energy.

3.  Deux objets (des vaisseaux spatiaux en fait) se sont heurtés dans un mur. Le premier objet a appliqué une force de10/13d'un Newton sur le mur et le deuxième objet a appliqué une force de6/7d'un Newton. Montre lequel a appliqué la plus grande force. (force = masse x accélération)

4.  Jose is hiking in the national park. He is on a6 3/4-mile hike and he makes four evenly spaced rest stops along the way. At what mile of the hike does he make his last stop?

5.  The kinetic energy (KE) of an object is one-half its mass times its velocity squared (1/2mv2). If a1 1/3-kg ball has a velocity of1/3m/s, what is its KE? (hint: don't forget to square the velocity)
