Question

34.) Two objects A and B are moving with velocities Va and Vb respectively along positive X-axis,
Draw the position-time graph correctly showing the velocity Of A and B?​

Answer 1

The ratio of velocities of A:B is

The two particles moves with different velocities acquiring two different slopes in displacement time graph. The velocity ratio of both will be calculated by knowing their velocity through –

Given that angle of inclination for particle A = 30 degree

Angle of inclination for particle B = 45 degree

Slope of the displacement time graph gives the velocity

Therefore, slope of A = velocity of A and slope of B = velocity of B  

Slope of A = velocity of A

Slope of A =   tan30

Velocity of A = tan30

Velocity of A = tan 30

Slope Of B = velocity of B

Slope of B = tamn45

Velocity of B = tan 45

Answer 2

Explanation:

the slope will come by 30and other is 45
