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=3.50sint+1.20sin2t. 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=ν0(cosθ)t, where ν0 is the initial velocity. θ 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?
