The acceleration of the body is provided by the tension in the rope.
<h3>What is centripetal acceleration?</h3>
The centripetal acceleration is given by a = v^2/r. v = velocity of the body, r = radius
a = (8.40 m/s)^2/(8.50 m)
a = 8.3 m/s^2
The tension in the rope is the force that provides the centripetal force in the rope.

One watt is defined as the energy consumption rate of one joule per second. 1W = 1J / 1s. One watt is also defined as the current flow of one ampere with voltage of one volt.
Answer:
Tides are very long-period waves that move through the oceans in response to the forces exerted by the moon and sun. They originate in the oceans and progress toward the coastlines where they appear as the regular rise and fall of the sea surface. When the highest part or crest of the wave reaches a particular location, high tide occurs; low tide corresponds to the lowest part of the wave, or its trough. The difference in height between the high tide and the low tide is called the tidal range. Tidal range is the height difference between high tide and low tide.
Answer:
time=4, answer choice A
time=5.5, answer choice B
Explanation:
This is taken from the kinematic equation, v=vo+(1/2)at^2
Velocity at time 4 = 30+(2.5)(4)^2
Velocity at time 5.5 = 30+(2.5)(5.5)^2
Velocity at time 4 seconds = 70 m/s
Velocity at time 5.5 seconds = 105.63 m/s
