A spring is being moved up and down. An object is attached to the end of the spring that undergoes a vertical displacement. The displacement is given by the equation $y = 3.50 sint + 1.20 sin2t$. Find the first two values of t (in seconds) for which y =0.

A ball is thrown off the edge of a building at an angle of 60° and with an initial velocity of 5 meters per second. The equation that represents the horizontal distance of the ball x is $x={{\nu}}_0(\cos \theta)t$, where ${{\nu}}_0$ is the initial velocity. $\theta$ is the angle at which it is thrown and $t$ is the time in seconds. About how far will the ball travel in 10 seconds?

Which of the following statement sare TRUE?
