Answer:
it is an upside-down image but the brain realizes it and corrects it in its orientation so we see it in right direction.
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.

Answer:
750W
Explanation:
Given parameters:
Weight = 1 x 10³N = 1000N
Distance = 1.5m
Time = 2s
Unknown:
Power = ?
Solution:
Power is the rate at which work is done
Work is the force applied on a body to move it through a particular distance
Work = force x distance
Power = 
Now, work = 1000 x 1.5 = 1500J
So;
Power = 
= 750W
Answer:
125 m
Explanation:
Given:
v₀ = 20 m/s
v = 0 m/s
a = -1.6 m/s²
Find: Δy
v² = v₀² + 2aΔy
(0 m/s)² = (20 m/s)² + 2 (-1.6 m/s²) Δy
Δy = 125 m
