Question

A body moving with uniform acceleration has a velocity of -11 cm/s
when its x coordinate is 3 00 cm If itsx coordinate 2 s later is -5
cm, what is the magnitude in cm/square of its acceleration?

Pratyay Ghosh · Accepted Answer

Distance travelled, s=-5-(+3)= -8 cm Initial velocity,
u=-11 cm/s time, t=2 s
We use,
s=ut+12at2⇒-8=-11×2+12×a×22⇒a=22-82=7
Therefore magnitude of acceleration in cm/s2 is 7
