Kinematics Question 358

Question: The distance travelled by a particle starting from rest and moving with an acceleration 43ms2 , in the third second is:

Options:

A) 6 m

B) 4 m

C) 103m

D) 193m

Show Answer

Answer:

Correct Answer: C

Solution:

distance travelled in the nth second is given by tn=u+a2(2n1)

Put u=0, a=43ms2,

n=3
d=0+43×2(2×31)=46×5=103m
