MULTIPLE CHOICE QUESTION
3 mins • 2 pts
A particle moves along a straight line and passes through a fixed point, O. The displacement, s meters, at time t seconds after the particle starts moving is given by s = 4 + 8t - t².
Calculate the instantaneous displacement in meters and determine the motion of the particle from the fixed point, O .
When t = 10
16 m to the left
16 m to the right
8 m to the right
4 m to the left
Answer explanation
just substitute t = 10 into the equation given
s = 4 + 8t - t²
s = 4 + 8(10) - (10)²
s = -16
thus, it moves 16 to the left
(negative sign shows that it moves to the left)

MULTIPLE CHOICE QUESTION
3 mins • 2 pts
Determine the velocity, v in terms of of t
(using the differentiation method)
s = 2t³ - 4t² + 2t + 1
v = 6t² - 4t + 2
v = 6t⁴ - 8t³ - 2t² + t
v = 12t - 8
v = 6t² - 8t + 2

Determine the v in terms of t
(differentiation)
s = t (2 - t)²
v = 2 - t
v = (2 − t)³
v = 3t² - 8t + 4
v = t (2t−1)

s = t(2t² − 9t − 5)
v = 6t² - 18t - 5
v = t² − 9t−5
v = t (4t−9)

s = t³ (3 + t)²
v = t² (6 + t)
v = 6t² + t³
v = 5t⁴ + 24t³ + 27t²
