An objects velocity vs time function is v(t)= (t^2-7t+10) m/sec. a) sketch the function b) What are the turning points?

An objects velocity vs time function is v(t)= (t^2-7t+10) m/sec.

a) sketch the function

b) What are the turning points? Explain why these are turning points

c) What is the objects acceleration at each of the turning points?

d) Suppose the objects position is x=18 m at t=3 sec. Write the objects position vs time function x(t)
