A ball is launched upward at 20 meters per second (m/s) from a 60 meter tall platform. The equation for the object’s height s at time t seconds after launch is s(t) = -4.9t^2+20t+60, where s is in meters. How long before the object hits the ground after launch?

Rectangle abcd is translated to get rectangle a’b’c’d’. rectangle abcd moves units along the x-axis to get rectangle a’b’c’d’. rectangle abcd moves units along the y-axis to get rectangle a’b’c’d’. the algebraic rule that describes this translation is t(x, y), where x = and y = .
