Hi guys,

I have the following problem:

At time = 0, a body is projected from an origin O with an initial velocity of 10ms-¹. The body moves along a straight line with a constant acceleration of -2ms-².

a) Find the displacement of the body from O when t = 7.

I have done this OK

b) How far from O does the body come to a instantaneous rest and what is the value of t then?

I have done this OK

c) Find the distance travelled by the body during the time interval t = 0 to t = 7.

I do not know this, help please
