Question

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?
A. -0.85 meters/second2
B. 1.16 meters/second2
C. -1.16 meters/second2
D. -0.9 meters/second2

Answer 1

Answer: C. -1.16 meters/second2

Explanation:

A= v/t (velocity/time)

in this case: v=7 and t=6

So, A= 7/6

A=1.16

The graph is decreasing so accelleration would be negative

A= -1.16 meters/second2
