Question : The distance travelled by a particle starting from rest and moving with an acceleration (4/3) m/s², in the third second is
a) 10/3 m
b) 19/3 m
c) 6 m
d) 4 m
Doubt by Trishna
Solution :
u=0 m/s
a=4/3 m/s²
Using Fourth Equation of Motion
u=0 m/s
a=4/3 m/s²
Using Fourth Equation of Motion
Snth = u+(a/2)[2n-1]
S3rd = 0 +[(4/3)/2][2(3)-1]
S3rd = 0+(2/3)[6-1]
S3rd = (2/3)×5
S3rd = 10/3 m
S3rd = 0 +[(4/3)/2][2(3)-1]
S3rd = 0+(2/3)[6-1]
S3rd = (2/3)×5
S3rd = 10/3 m
Hence, a) 10/3 m is the correct option.
