<h3>What is angular acceleration?</h3>
- The temporal rate at which angular velocity changes is known as angular acceleration. The standard unit of measurement is radians per second per second. Therefore, = d d t. Rotational acceleration is another name for angular acceleration.
- Angular velocity divided by acceleration time can be used to define angular acceleration. (t). As an alternative, use pi times the drive speed (n) divided by the acceleration time (t) times 30. Radians per second squared (Rad/sec2) is the standard SI unit for rotational acceleration resulting from this equation.
- To calculate angular velocity, we can use one of three formulas. The definition itself provides the first. Theta = position angle, t = time, and w = angular velocity, where w = angular velocity, theta = position angle, and t = time. Angular velocity is the rate of change of an object's position angle with respect to time.
- The symbol for angular acceleration is, and it is measured in rad/s2, or radians per second square.

The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere. Radiatively active gases in a planet's atmosphere radiate energy in all directions

Answer:
a) Vf = 4.95 m/s
b) t = 0.51s
Explanation:
take downwards as positive.
let Vf be the final velocity as the cucumber reach the bottom of the bin and Vi be the initial velocity of the cucumber when they dropped.
a ) from equations of motion:
(Vf)^2 = (vi)^2 +2g×(x - x0) ,
<em>since x0 = 0 m and Vi = 0 m/s.</em>
Vf = \sqrt{2g×(x)} = \sqrt{2(9.8)×(1.25)} = 4.95 m/s, downwards
therefore, the cucumber will reach the bottom of the bin with a speed of 4.95 m/s.
b) from equations of motion:
Vf = Vi + g×t
Vi = 0 then:
t = Vf/g = 4.95/9.8 = 0.51 s
therefore, the cucumber will take 0.51 seconds to reach the bottom of the bin.
