A particle P is projected from the origin O so that it moves in a straight line.
Question:
A particle P is projected from the origin O so that it moves in a straight line. At time t seconds after projection, the velocity of the particle, v ms-1, is given by v = 9t2 – 63t + 90.
i. Show that P first comes to instantaneous rest when t = 2.
ii. Find the acceleration of P when t = 3.5.
iii. Find an expression for the displacement of P from O at time t seconds.
iv. Find the distance travelled by P
a. In the first 2 seconds,
b. In the first 3 seconds,
