When the ball goes upward, the velocity is decreasing. Therefore, the kinetic energy is decreased. The potential energy when the ball's height increases also increases. When the ball reaches maximum, the velocity becomes zero and the kinetic energy is minimum.
The banking angle of curved road to allow to move without slipping is 11.53 ⁰.
<h3>
Banking angle of curved road</h3>
The banking angle of curved road is calculated as follows;
V(max) = √(rg tanθ)
where;
- r is radius of the curve
- g is acceleration due to gravity
V² = rg tanθ
tanθ = V²/rg
tanθ = (61²)/(1860 x 9.8)
tanθ = 0.204
θ = arc tan(0.204)
θ = 11.53 ⁰
Thus, the banking angle of curved road to allow to move without slipping is 11.53 ⁰.

Answer:wave travel
Explanation:Because gravity pulls the water in the crest downward .Forced out from beneath the falling crests ,the falling water pushes former troughs upwards and the wave moves to a new position causing a disturbance.
