What is the speed of the 6 kg block at rest?

Oct 13, 2009 · What is the the speed of the block when it leaves the track? Correct answer: 7. 30529 m / s (tolerance ± 1 %). Explanation: From Eq. 8, we have v x = s-g x 2 2 h 2 = s-(9. 81 m / s 2) (4. 78 m) 2 2 (-2. 1 m) = 7. 30529 m / s. Alternate Solution: From Eq. 7, we have v x = p 2 g (h 1-μ ‘) = 2 (9. 81 m / s 2) h (3. 00005 m)-(0. 2) (1. 4 m) i 1 / 2

How often do asteroid collisions happen?

Astronomers estimate that a 2.0-km diameter asteroid collides with the Earth once every million years. The collision could pose a threat to life on earth. a) Assume a spherical asteroid has a mass of 3200 kg of each cubic meter of volume and moves toward the Earth at 15 km/s. How much destructive energy could be released when it embeds itself in ...

Is frictional torque negative?

Frictional torque is negative! So when you subtrac t it from the other side, it is really an addition. A helicopter rotor blade has three long thing rods. a) If each of the three rotor blades is 3.75 m long and has a mass of 135 kg, calculate the moment of inertia of the three rotor blades about the axis of rotation.
