## Find the Acceleration Given a Position Function| University Physics

An object moves along the x-axis. The position as a function of time is given by c(t)=at^3+bt+c. What is the object's acceleration at time t = 0.50 s?

## Find Acceleration Diagram from Velocity Vector Diagram| University Physics

The figure above shows the motion diagram for an object. If the x-axis is chosen as shown (positive to the right), which of the diagrams below best represents the corresponding acceleration vs time graph? (In the graph, later time is to the right).

## Pendulum’s acceleration at the lowest point| University Physics

In a physics lab, a pendulum hung from the ceiling slowly swings back and forth. Select the arrow that best indicates the direction of the pendulum's acceleration when it reaches the lowest point moving from left to right.

## Rank the diagrams according to the x-component of the acceleration| University Physics

The figure below shows six different motion diagrams. The separation between dots is in the same scale in all diagrams, and the time interval between dots is also the same for all of them. The direction of the positive x-axis is also shown. Rank the diagrams according to the x-component of the acceleration. (Positive is greater than negative)

## Finding where the magnitude of acceleration is constant from given motion diagrams| University Physics

The figure below shows four different motion diagrams. The green arrows represent the velocity vectors. For which of the diagrams can you say that the magnitude of the acceleration is clearly changing as a function of time?

## Determine the instantaneous acceleration from a velocity-time graph| University Physics

The graph below shows the velocity versus time graph for a certain object. What is the object's acceleration at time t = 5 s?

## College Physics by Openstax Problem 2.33

An unwary football player collides with a padded goalpost while running at a velocity of 7.50 m/s and comes to a full stop after compressing the padding and his body 0.350 m.

## College Physics by Openstax Problem 2.32

A woodpecker’s brain is specially protected from large decelerations by tendon-like attachments inside the skull. While pecking on a tree, the woodpecker’s head comes to a stop from an initial velocity of 0.600 m/s in a distance of only 2.00 mm.
