Question

Plz answer both the questions with proper solution

Answer 1

Answer:

1. a. Angular acceleration is the time rate of change of the angular velocity and is usually denoted by α and expressed in radians per second. For the case in which the angular velocity is uniform.

b. Linear acceleration and angular acceleration are directly proportional. The greater the angular acceleration is, the larger the linear acceleration is, and vice versa.

2.The time of flight depends on the initial velocity of the object and the angle of the projection, θ . When the point of projection and point of return are on the same horizontal plane, the net vertical displacement of the object is zero.
