8. The speed of an object is depicted in the following velocity-time graph. Determine the acceleration during interval `A`, `B` and `C`.
8. The speed of an object is depicted in the following velocity-time graph. Determine the acceleration during interval A, B and C.  `a= (∆v)/(∆t) `
A:
`a= 1\ m//s^2`
B:
`a= 0`
C:
`a= -4\ m//s^2`
Equation:
`a= (∆v)/(∆t) `
A:
`a= (4\ m//s - 1\ m//s)/(3\ s - 0) `
`a= 1\ m//s^2`
B:
`a= (4\ m//s - 4\ m//s)/(5\ s - 3\ s) `
`a= 0`
C:
`a= (0\ m//s - 4\ m//s)/(6\ s - 5\ s) `
`a= -4\ m//s^2` |
