Question

A particle starts from rest at the origin and moves along
the positive x direction. Its acceleration a versus position
x graph is shown in the figure. The velocity of the particle
at x = 6 m is
​​

Answer 1

Answer:

-20m/s

Step-by-step explanation:

at 4s velocity become 0.

after 2s velocity is in negative= -2× 10

-20m/s

Answer 2

Displacement in V-T curve is area under the curve.

Displacement in V-T curve is area under the curve.Position at time t (=5 s) = Area under graph up to 5 second

Displacement in V-T curve is area under the curve.Position at time t (=5 s) = Area under graph up to 5 second1 /2 ×2×2+2×2+3×1

=9m
