The kinetic energy of a moving object is related to its mass and velocity by the formula E_{k}= 1/2mv^{2}, where E_{k} is the Kinetic energy in joules, m is the mass of the object in kg, and v is the velocity in metres per second. What are the possible veolocited for a 3 kg object with a kinetic energy of less than 600 J?

Negative velocities are acceptable and represent the opposite direction of a positive velocity.

A special event organizer wants to get the word out to 100 000 teens in the area about a concert coming up in three months. By posting the event on the musician’s website, 100 teens in the area will find out about the event in the first week. Research suggests that each of those teens will tell four new teens about the event, and those friends each will tell four more teens about it. a. How many times does this pattern need to continue until 100 000 teens know about the event?

A famous fractal called the Sierpinski Triangle starts with one black triangle. The triangle is then cut into four equal pieces, and the three outer triangles are coloured black and the inner triangle is white. Each of the three black triangles is again divided into four equal triangles, and the three outer triangles are shaded black. a. Suppose the area of the first triangle is 100 cm2. Determine the black shaded area in the second triangle. Do the same for the third triangle. b. Write the general term describing the shaded area of the nth Sierpinski Triangle.
