Question 131: Motion in 1D

Question

The displacement-time graphs of two moving particles make angles of 30$$^\circ$$ and 45$$^\circ$$ with the x-axis as shown in the figure. The ratio of their respective velocity is

Accepted Answer

Slope of x-t curves gives the velocity
$$\Rightarrow$$ Ratio $$ = {{	an 30^\circ } \over {	an 45^\circ }} = {1 \over {{{\sqrt 3 } \over 1}}} = 1:\sqrt 3 $$

Answer

$$\sqrt3$$ : 1

Answer

1 : 1

Answer

1 : 2
