You have three known variables:
Acceleration -

Time -

Initial Velocity -

For the first part of your question:

For the second part of your question:

This still needs to be converted to m/h:
relation between linear velocity and angular velocity is given as

here
v = linear speed
R = radius
= angular speed
now plug in all data in the equation



so rotating speed is 60.9 rad/s

i think the reason was because of the pangea theory that continents where once one big continent and over time it began to split
Answer:
the material
Explanation:
weight is defined as the amount of force on the object because of gravity. ping pong balls and bouncy balls are made out of different materials that are different weights. most bouncy balls are also not hollow, unlike ping pong balls. these factors affect the weight of these objects.
One comparison is that both people in the cars (whether they were wearing a seat belt or not) is that they sustain injuries. People are obviously going to get hurt in a crash. A prime difference though is how big of an injury it is. People who were wearing seat belts at the time of a crash are less likely to have serious injuries, while those who weren't wearing seat belts have a higher possibility of sustaining really serious injuries.
