The correct answer is A continúe moving with constant velocity
Answer:
Speed; v = 17 m/s
Explanation:
We are given;
Radius; r = 110m
Angle; θ = 15°
Now, we know that in circular motion,
v² = rg•tanθ
Thus,
v = √(rg•tanθ)
Where,
v is velocity
r is radius
g is acceleration due to gravity
θ is the angle
Thus,
v = √(rg•tanθ) = √(110 x 9.8•tan15)
v = √(288.85)
v = 17 m/s
Final speed 10.0 rn/s Change in time = 3 seconds The acceleration of the skater is 2.7 meters per second Relationship per second. 3.
Answer:
They are changes in bonding energy between the molecules. If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance. ... At the moment of melting the average kinetic energy of the molecules does not change.
