When a base ball by a batter, the height of the ball, h(t), at time t, is determined by the equation `h(t)=-16t^(2)+64t+4`, where `tge0`. For which interval of time, in seconds, is the height of the ball at least 52 feet above the playing field?

The height h , in feet , of a ball shot upward from a ground level spring gun is described by the formula h=-16t^2+48t . Where t is the time in seconds. What is the maximum height , in feet , reached by the ball ?

The height of a ball thrown into the air with an initial vertical velocity of 24 fts from a height of 6 feet above the ground is given by the equation: h=16t^(2)+24t+6, where t is the time in seconds,for the ball has been in air. After how many seconds is the ball at a height of 14 feets

The height (in meters) at any time t (in seconds) of a ball thrown vertically varies according to equation h(t)=-16t^(2)+256t . How long after in seconds the ball reaches the hightest point

The height (in meters) at any time t (in seconds) of a ball thrown vertically varies according to equation h(t)=-16t^(2)+256t . How long after in seconds the ball reaches the hightest point

The height (in meters) at any time t (in seconds) of a ball thrown vertically varies according to equation h(t)=-16t^(2)+256t . How long after in seconds the ball reaches the hightest point

When a ball is thrown straight up at an initial velocity of 54 feet per second. The height of the ball t seconds after it is thrown is given by the function h(t)=54t-12t^(2) . How many seconds after the ball is thrown will it return to the ground?

A soccer ball is kicked upward from gound level with an initial velocity of 52 feet per second. The function h(t)=-16t^2+52t gives the ball's height , in feet , after t seconds. For how many seconds, to the nearest tenth of a second , is the ball at least 20 feet above the ground ?

A stone thrown vertically upward satisfies the equation s= 64 t -16t^(2) where is in meter and t is second .What is the time required to reach the maximum height ?

A model rocket is launched vertically into the air such that its height at any time, t, is given by the function h(t)=-16t^(2)+80t+10 . What is the maximum height attained by the model rocket?

Soumya throws a ball upwards, from a rooftop, 80 m above. It will reach a maximum height and then fall back to the ground. The height of the ball from the ground at time 't' is 'h', which is given by h=-16t^(2)+64t+80 What are the two possible times to reach the ball at the same height of 128 m ?
