Answer:
0.4rad/s²
Explanation:
Angular acceleration is the time rate of change of angular velocity . In SI units, it is measured in radians per second squared (rad/s²)
w1 = 4rad/s, w2 =2rad/s, t = 5sec, r = 0.30m
a = ∆w/t
a = (w2 - w1)/t
a = (2 - 4)/5 = -2/5 =
a = - 0.4rad/s²
The -ve sign indicates a deceleration in the motion
Good luck
The situation is an example of an arithmetic progression through the data 90, 120, 150, .. . In this case, the arithmetic difference is 30. The expression that applies here is an = 90 + 30 * (n - 1) where n is the order of the term to be determined. If n is 8, then the height is equal to a. 300 feet.
Distance = rate x time. Your rate is 2.5 meters per second and your time is 45 minutes. So d=2.5 x 45. Your distance is 112.5 meters.
