I = mΔv
I = 2.5 x (7.5 - 0) = 18.75 kg.m/s
Now, considering that the ball´s initial velocity was zero, we have:
1.45 x 0 + 2.5 x 7.5 = 1.45 x V
1.45V = 18.75
V = 12.93 m/s
Answer:
0.7757 rev/s
Explanation:
d = Diameter of the tornado = 53 m
r = Radius of the tornado = 53/2 = 26.5 m
v = Velocity of wind = 465 km/h
Converting velocity to m/s
Angular velocity
∴ Angular velocity is 0.7757 rev/s
Answer:
When you jump down, your kinetic is converted to potential energy of the stretched trampoline. The trampoline's potential energy is converted into kinetic energy, which is transferred to you, making you bounce up. At the top of your jump, all your kinetic energy has been converted into potential energy. Right before you hit the trampoline, all of your potential energy has been converted back into kinetic energy. As you jump up and down your kinetic energy increases and decrease.
