a)
Kinetic energy (KE) = 1/2 m v^2
Where:
m = mass = 1260 kg
v = speed = 66.3 km/h = 18.42 m/s
Replacing:
KE = 1/2 (1260 kg ) (18.42 m/s )^2 = 213,756.7 J
The first and third choices could both do it, but the first choice makes a much better, clear demonstration.
Answer:
16m/s
Explanation:
Therefore, the speed after 8 seconds is 16m/s
Answer:
Noise making has led to loss on hearing.
Explanation:
Supposing you like engaging in parties because of the noise of the sound system it can cause loss on hearing if continued for long
Answer:
one at the edge
Explanation:
The relation between the linear velocity and the angular velocity is given by
v = r x ω
Where, v be the linear velocity, ω be the angular velocity and r be the radius of the circular path.
As the angular velocity is constant, thus, the linear velocity depends on the radius of circular path.
So, the horse which is near to the edge has maximum radius of circular path in which it is rotating. So, the horse which is at the edge of the merry go round has maximum linear speed.
