The velocity after 10 seconds is ft sec library d. The acceleration is ft/sec Enter your answer in each of the answer boxes ezes can be taken for sample

Explanation / Answer

s(t)=-16t^2

a)

velocity after 2 second

s(t)=-16t^2

v(t)= s'(t)= -32t

t=2

v(2)=-64feet/s

b)

t=5

v(5)= -160ft/s

c)

t=10

v(10)=-320ft/s

d)

acceleration a(t)=s''(t)

a(t)=-32ft/s^2
