The velocity versus time graph of particle A is tangent to the velocity versus time graph for particle B at point O. What is the acceleration of the particle A at point O?

The velocity versus time graph of particle A is tangent to the velocity versus time graph for particle B at point O What is the acceleration of the particle A a class=

Respuesta :

As velocities are tangent, the value of both Particle A and Particle B would be same for that point O (Intersecting point)

a = v / t
Here, v = 7, t = 6
So, a = 7/6
a = 1.17 
As the graph is decreasing, value of acceleration would be negative.
So, a = -1.17 m/s²

In short, Your Answer would be Option C

Hope this helps!
