The constant velocity v = 2 m/s. What are the magnitudes of the velocity and acceleration of point P when x = 0.25 m? Download solution

The 1 kg slider A is pushed along the curved bar by the slotted bar. The curved bar lies in the vertical plane, and its profile is described by r= 2(𝜃/2&pi:+1) m, where 𝜃 is in radians. The angular position of the slotted bar is 𝜃 = 2t rad, Determine the radial and transverse components of the total external force exerted on the slider when 𝜃= 120˚. Download solution

The mass A attempts to dock with the mass B, 15. Their masses are m_A= 18 kg and m_B = 6.6 kg. The mass B stationary relative to the reference frame, and the mass A approaches velocity V_A= (0.2 i + 0.3 j - 0.02 k) m/s.

(a) If the first attempt at docking is successful, what is the velocity of the centre mass of the combined masses afterwards?

(b) If the coefficient of restitution of resulting impact is e = 0.95, what are the velocities of the two masses after impact?
