Question

A particle moves along the x axis. Its position varies with time according to the expression
() = − +
m. Determine the displacement and average velocity of the particle in the
time interval t = 0 s to t = 1 s and from t = 1 s to t = 3 s​

Answer 1

Answer:

The displacement is given as: y=ut+21at2

where, u is the initial velocity and a is the acceleration

Comparing with given expression: 

y=−5t+6t2+2

u=−5m/s, a=12m/s2

So initial velocity is −5 m/s
