Question

the displacement time graphs of two moving particles make angles of 30 and 45 with the x - axis.the ratio of the two velocities

Answer 1

Answer   is. V1/V2=  1:root3

Answer 2

Answer: √3:1

Explanation:slope of displacement time graph gives velocity (v1/v2=tan45°/tan30°)

v1/v2=1/(1/√3)

v1/v2=√3/1

v1:v2=√3:1
