Consider the following descriptions of the vertical motion of an object subject only to the acceleration due to gravity. begin with the acceleration equation a(t)equals=v primev′(t)equals=g, where gequals=minus−9.8 m divided by s squared9.8 m/s2.
a. find the velocity of the object for all relevant times.
b. find the position of the object for all relevant times.
c. find the time when the object reaches its highest point. what is the height?
d. find the time when the object strikes the ground. a softball is popped up vertically (from the ground) with a velocity of 27 m divided by s27 m/s.

none, its a machine

i will answer your question if you answer mine

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.

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.
