Suppose an object is dropped from a lunar cliff and its speed in ft/sec. after t seconds is given by v(t)=5.3t
If the object lands after 5 seconds, how high (in ft) is the cliff?
object is thrown down from a cliff with an initial speed of 4 feet per sec, and its speed in ft/sec after t seconds is given by s(t)=32t+4.
If the object lands after 8 seconds, how high (in ft) is the cliff?
A train travels along a track and its speed (mph) is given s(t)=29t for the first half hour. Its speed is constant and equal to s(t)=29/2 after the first half hour. t is in hours.
How far (miles) does the train travel in the first hour?I think I am supposed to combine the areas of two shapes.
