Explanation:
a)
θ = 4.91 + 9.7t + 2.06t² when t = 0
θ = 4.91 rad
θ = 4.91 + 9.7t + 2.06t²
ω = dθ/dt = 9.7 + 2.06t, when t =0
ω = dθ/dt = 9.7 + 0
ω = 9.7 rad/s
α = d²θ/dt² = 2.06
α= 2.06 rad/s²
b) please use same method above for t = 2.94 s
A convergent plate movement happened, this movement also cause the Himalayan mountains, where Mt. Everest is located.
Hope this helps!

Answer:
Energy storage plays an important role in this balancing act and helps to create a more flexible and reliable grid system. For example, when there is more supply than demand, such as during the night when low-cost power plants continue to operate, the excess electricity generation can be used to power storage devices.

Explanation:
From the question we are told that
The mass of the golf ball is
The angle made is
The range of the golf ball is
The duration of contact is
Generally the range of the golf ball is mathematically represented as
Here v is the velocity with which the golf club propelled it with, making v the subject
=>
=>
Generally the change in momentum of the golf ball is mathematically represented as
here u is the initial velocity of the ball before being stroked and the value is 0 m/s
=>
Generally the average force of impact is mathematically represented as
=>
=>
