Two smooth disks A and B each have a mass of 0.5 kg. If both disks are moving with the velocities shown when they collide, determine their final velocities just after collision. The coefficient of restitution is e = 0.75

The angular velocity of a rotating disk is defined by ω = (4t^2 + 9t + 3) rad/s, where t is in seconds. If the disk has a radius of 0.8 m: determine the magnitude of the velocity and acceleration of the disk when t=1.0 second.

QUESTION 6: Two smooth disks A and B each have a mass of 0.5 kg. If both disks are moving with the velocities shown when they collide, determine their final velocities just after collision. The coefficient of restitution is e = 0.75. (VA)1 = 6 m/s A B (VB)1 = 4 m/s X

A ship has a metacentre height of 0.90 m and its period of rolling is 20 seconds. The relevant radius of gyration is nearly

A 400-kg satellite was placed in a circular orbit 1500 km above the surface of the earth. At this elevation the acceleration of gravity is 6.43 m/s?. Determine the kinetic energy of the satellite, knowing that its orbital speed is 25.6 x 10 km/h. The small cart has a speed vA = 4 m/s as it passes point A. It moves without appreciable friction and passes over the top hump of the track. Determine the cart speed as it passes point B. A=4 m/s 1.8 m B A 1-lb stone is dropped down the "bottomless pit" at Carlsbad Caverns and strike the ground with a speed of 95ft/s. Neglecting air resistance, determine (a) the kinetic energy of the stone as it strikes the ground and the height h fro which it was dropped, (b) Solve Part a assuming that the same stone is dropped down a hole on the moon (Acceleration of gravity on the moon = 5.31 ft/s².) A package is projected up a 15° incline at A with an initial velocity of 8 m/s. Knowing that the coefficient of kinetic friction between the package and the…

Two steel spheres of diameters d, and d₂ where d₂ = 2d₁, are dropped from rest at the free surface of a deep well. If their drag coefficients are independent of Reynolds number, the ratio of their terminal velocities, V₁/V₂ is
