4 Baloo the Bear is back to his old tricks. This time he stole a shopping cart
and decided to race it down a hill. The acceleration of a shopping cart
rolling down the hill is 0.85m/s2. If he trips and push the cart forward with
an initial velocity of 2m/s, How fast is the cart going after 4 seconds? *

yup its correct its: c) b b

graphing motion: mastery test

209be

what is the instantaneous acceleration of

the particle at point b?

0 meters/second?

10 meters/second?

12 meters/second?

velocity imetersisecond

15 meters/second?

20

time (seconds)

answer: 0 meters/second^2

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
