Question

3. When a body is thrown up. What is the lindi velocity IC ) 4. A horizontal line in graph, distance on y-axis and time on x-axis, represent following questions. Each questions carries TWO marks.​

Answer 1

Answer:

Velocity will first decrease according to the equation v=u−gt where u is initial velocity(at t=0 ) so the graph can't start from origin because u is not zero as thrown with some velocity and v is final velocity. then t=u/g the v will become zero then it will start increasing in opposite direction , if the upward direction is taken as positive then the downward velocity will be negative.

Option A is correct as after certain point velocity becomes negative and get increasing.
