A particle is moving along positive x direction and experiences a constant acceleration of `4 m//s^(2)` in negative x direction. At time `t = 3` second its velocity was observed to be `10 m//s` in positive x direction.
(a) Find the distance travelled by the particle in the interval `t = 0` to `t = 3 s`. Also find distance travelled in the interval `t = 0` to `t = 7.5 s`..
(b) Plot the displacement – time graph for the interval `t = 0` to `7.5 s`.

Answer

(a) `48m, 68.5 m`
(b) `(##IJA_PHY_V01_C02_E01_065_A01##)`
