Question 154: Motion in 1D

Question

The distance travelled by a particle starting from rest and moving  with an acceleration $${4 \over 3}$$m s
$$-$$2
, in the third second is

Accepted Answer

distance travelled in nth seconds
S(n th) = u + $${a \over 2}(2n - 1)$$
Here u = 0, $$a$$ = $${4 \over 3}$$m s
$$-$$2
, n = 3
S(3 rd) = $${4 \over {3 	imes 2}}(2 	imes 3 - 1)$$ = $${{10} \over 3}$$ m

Answer

$${{10} \over 3}$$ m

Answer

$${{19} \over 3}$$ m

Answer

6 m

Answer

4 m
