A hoop with a mass of 1.2 kg is rotating about a fixed axis through its center and perpendicular to the plane. It has an angular acceleration of 2.0 rad/s2. A point on the rim has a tangential acceleration of 0.80 m/s2. (a) Find the radius of the hoop. (b) At a certain instant, a point on the rim has a tangential velocity of magnitude 3.4 m/s. What is the magnitude of the tangential velocity 2.0 s later? (c) If all the mass is in the rim of the hoop, find the hoop's Irot.

the results is a decrease in air temperature with an increase of altitude.

explanation:

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.
