Graphs of the velocity functions or two particles are shown, where t is measured in seconds.
a.
When is the particle in figure (a) speeding up? (Enter your answer using interval notation.)
When is the particle in figure (a) slowing down? (Enter your answer using interval notation.)
b.
When is the particle in figure (b) speeding up? (Enter your answer using interval notation.)
When is the particle in figure (b) slowing down? (Enter your answer using interval notation.)
If a ball is thrown vertically upward with a velocity of 96 ft/s, then its height after t seconds is s = 96t - 16t2.
What is-the maximum height reached by the ball?
What is the velocity of the ball when it is 128 ft above the ground on its way up?
What is-the velocity of the ball when it is 128 ft above the ground on its way down?
