Answer:
A) θmin= 76°.
Explanation:
Given that
Speed of cannonball = Vo
Lets take θ is the angle measure from horizontal
We know that
Range R
Height h
Given that h should be larger than R
h > R
θ >75.96°
So minimum angle should be 75.96° or 76°.

<h2>The magnitude 24 (
) of the acceleration of the particle when the particle is not moving.</h2>
Explanation:
Given,
A particle moving along the x-axis has a position given by
m ........ (1)
To find, the magnitude ( ) of the acceleration of the particle when the particle is not moving = ?
Differentiating equation (1) w.r.t, 't', we get
⇒ ....... (2)
⇒
⇒
⇒ t = 2 s
Again, differentiating equation (2) w.r.t, 't', we get
Put t = 2, we get
Thus, the magnitude 24 ( ) of the acceleration of the particle when the particle is not moving.
