Power = work /time
and W = force * dis
W = 96 * 3.046 J = 292.44 J
P = 292.44 / 4.6 = 63.575 watt
sry cant help with that there isnt enough info on it :(
Answer:
A.
The balls stick and move together.
Explanation:
When a bodies undergo perfectly inelastic collision, the two bodies stick together after the collision and begins to move.
In this collision, kinetic energy is not conserved. For perfectly elastic collision, the two bodies conserve kinetic energy and begin to move apart.
Kinetic energy is not conserved because some of the energy gets converted into other forms of energy.
Answer:
W = 1,049 10⁹ J
Explanation:
Work is defined by the relation
W = F. d = F d cos θ
where tea is the angle between the forces and the displacement.
The total work is the sum of the work of each tug.
Tug 1
W₁ = F d cos θ₁
the angle measured from the positive side of the x-axis is
θ₁ = 14 + 90 = 104º
tugboat 2
W₂ = F d cos θ₂
θ₂ = 14
we substitute
W = F d cos θ₁ + F d cos θ₂
W = F d (cos θ₁ + cos θ₂)
let's calculate
W = 1.80 10⁶ 800 (cos 104 + cos 14)
W = 1,049 10⁹ J
