Suppose the position of an object moving in a straight line is given by s(t) = t^2+5t+2.

a) Find the average velocity between t = 1 and t=5

b) Find the instantaneous Velocity t=1 and t=5

Respuesta :

Answer:

Step-by-step explanation:

Finding the average velocity for time t=1 and t= 5

For t^2+ 5t+ 2

Putting 5 and 1 in to the equation

= (5^2)-(1^2) + 5(5-1)+ 2

= 25-1+ 5*4+2

=24+20+2

=46m/s

For instantaneous velocity

ds/dt is found

Which gives 2t+ 5

Putting t= 5 15

Putting t= 1. 7

Subtracting the answer 8m/s.
