Q4.13Multiple correct
Following are four differrent relations about displacement, velocity and acceleration for the motion of a particle in general. Choose the incorrect one (s) :
- (a)v av = [ v(t1 ) + v(t 2 )] r(t 2 ) − r(t1 )
- (b)v av = t 2 − t1
- (c)r = ( v(t 2 ) − v(t1 )) (t 2 − t1 ) v(t 2 ) − v(t1 )
- (d)a av = t 2 − t1
