Question

a particle moves with constant acceleration for 3 seconds, during which time it travels 27m.
it then moves with constant velocity and during the nest 5 seconds travels 60m.

so, whats the acceleration of the particle in the first 3 seconds?

and what was the initial velocity of it??

thanks :)

Answer 1

6 m/s

Answer 2

Can you see how?

Answer 3

Work out from the second part
s=vt
60=v*5
v=12m/s
Now for the first part
s=(v+u)*t/2
27=(12+u)*3/2
u=6

Answer 4

thanks :)
