height of helicopter above ground is given as h = 3t^3, where h is in meters and t is in seconds. After 2.00s the helicopter drops a bag. How long after is is released does the bag reach the ground?I know the answer is 7.96s, but do not know how to find it.
An object moves up and down. Its height, h in feet, is a function of time, t in seconds. It is known that • The domain is (-2,4). • The initial height is h(0) = 7 feet. • The graph of the velocity is h' (ft/s) 12 А. t(s) 1 -8 -12 1. What intervals is the height is increasing or decreasing? Enter answers using interval notation. Enter multiple intervals as comma-separated list. increasing (0.2) decreasing (-2,0), (2, 4) 2....

The height, h, in metres, above the ground of a rider on a Ferris wheel can be modelled by the equation:h= 10 sin ((pi/15 t) - 7.5) + 12 where t is the time, in seconds.At t=0, the rider is at the lowest point. Determine the first two times that the rider is 20 m above the ground, to the nearest hundredth of a second.
the height , h(t) in metres of the trajectory of a football is given by h(t) = 2+28t-4.9t^2, where t is the time in flight, in seconds . Determine the maximum height of thefootball and the time wehn the height is reached
