An unwary football player collides with a padded goalpost while running at a velocity of 8.50 m/s and comes to a full stop after compressing the padding and his body 0.210 m. (a)
What is his deceleration in m/s2? (Enter the magnitude.)
m/s2
(b)
How long in seconds does the collision last?

1400 kg car has a speed of 27 m/s. if it takes 7 s to stop the car, what is the impulse and the average force acting on the car?

The image below shows numerous volcanic mountains in the pacific northwest. what is the most likely cause of the volcanic and earthquake activity in this region?

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.
