Problem no 4: Find the velocity of body A after moving a distance of 10ft from rest. Assume that the pulleys are weightless and frictionless. (v = 7.65ft/s)
` Problem no. 5 What distance will body A move if its velocity changesfrom 6ft per sec to 12 ft per sec?
To what distance will block A attain a velocity of 12ft/s from rest? Determine the velocity obtained by block A after moving a distance of 12ft from its initial position.
A 40lb collar rests against its vertical guide, compute the velocity of the collar after it has fallen 7ft from rest from its initial position. Neglect the friction of the collar. The unstretched length of the spring is 3ft. (18.2ft/s)
The 0.31-kg mass slides on a frictionless wire that lies in the vertical plane as shown. The ideal spring attached to the mass has a free length of 80 mm and a stiffness of 120 N/m. Calculate the smallest value of the distance “b” if the mass is to reach the end of the wire at B after being released from rest at A. What is the velocity immediately before stopping at B? If the mass is released at b = 100 mm, how high will the mass be?
A particle with a mass of 0.75kg with an initial velocity of 6m/s at time t = 0sec is shown. Forces F1 and F2 acting on the particle changes their magnitude with time according to the graphical schedule shown.
Compute the vertical component of the final velocity at time t = 3 sec. (14.54) Compute the resultant velocity at time t = 3 sec. (15.77) Determine the direction of the velocity of the particle measured from the x-axis (counterclockwise)( 112.8)
Two bodies 0f 8kg and 6kg respectively move with velocities as shown. Determine the velocity of each body directly after impact if the coefficient of restitution is 0.60. The velocities of two collars before impact are shown. If after impact the velocity of collar B is observed to be 9m/s to the right, determine the coefficient of restitution between the collars. The steel ball A shown strikes the steel plate B with a velocity of 20m/s and rebounds from the plate with a velocity of 16m/s as shown. Determine the coefficient of restitution. In the oblique central impact shown, the coefficient of restitution is 0.80. The flat disk shown, slide on a smooth horizontal surface. Determine the final velocity of each disk directly after impact. A ball is thrown from a position 3.o m above the ground to the roof of a 25m high bi=uilding as shown if the initial velocity of the ball is 25m/s, inclined at an angle of 600 with the horizontal, determine the horizontal distance D from the point where the ball is thrown to where it strikes the roof.
