At t=10 ~\text{s}t=10 s, a particle is moving from left to right with a speed of 5.0 ~\text{m/s}5.0 m/s. at t=20 ~\text{s}t=20 s, the particle is moving right to left with a speed of 8.0 ~\text{m/s}8.0 m/s. assuming the particle’s acceleration is constant, determine its average acceleration. assume positive is on the right.

to the left.

Explanation:

We can use the equation where v is the velocity at time t and the velocity at . Since we want the acceleration we write this equation as:

Considering the direction to the right as the positive one, we have at , and at , so we substitute:

Where the minus sign indicates it is directed to the left.

hi there if you are asking for conformation that wavelingth is the correct answer is wrong it is the answer is frequency. : )

i hope this you out, have a wonderful day

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
