(OQ The accelerations of a particle as seen from two framess of a part

1.	(OQ The accelerations of a particle as seen from two framess of a particle as seen fromS, and S, have equal magnitude) 4 m/s(a) The frames must be at rest with respect to eachother.(b) The frames may be moving with respect to each otherbut neither should be accelerated with respect to theother.(c) The acceleration of S, with respect to S, may eitherbe zero or 8 m/s.(d) The acceleration of S2 with respect to S, may beanything between zero and 8 m/s 2
Answer» suppose the acceleration of particle is a3and for frame s1 , it is a1. and for frame s2 , it is a2 now from frame 1.the magnitude of acceleration of particle is 4m/s²so, \|a3-a1\| = 4 from frame 2.the magnitude of acceleration of particle is 4m/s²so, \|a3-a2\| = 4 on adding we can get max acceleration of 8 and minimum acceleration of 0.since acceleration is added and subtracted vectorily so the relative acceleration between s1 and s2 can be in between 0 to 8. option D

Answer»

suppose the acceleration of particle is a3and for frame s1 , it is a1. and for frame s2 , it is a2

now from frame 1.the magnitude of acceleration of particle is 4m/s²so, |a3-a1| = 4

from frame 2.the magnitude of acceleration of particle is 4m/s²so, |a3-a2| = 4

on adding we can get max acceleration of 8 and minimum acceleration of 0.since acceleration is added and subtracted vectorily

so the relative acceleration between s1 and s2 can be in between 0 to 8.

option D
