Q4 2. A ball is launched with an initial velocity of Vo = 4.5 m/s from point P at a 30° sloped surface with an angle of 0. The ball lands at point B, which is 0.6 m higher than point A. Determine the launch angle 0 of the ball, the impact velocity at B (vB), the angle vg makes with the horizontal and the duration of the flight. Also determine the radius of curvature of the path and the rate of change of the speed of the ball at point C, where its trajectory makes an angle of 60° with the negative x-axis. g 9.81 m/s-.
Need solution of part third for Force (F) in lb. If you are sure then only solve otherwise skip it. Don't post incorrect solution, check twise before uploading solution. Thank you ?
The 0.56 kg ball strikes the rough ground and rebounds with the velocity v2 as shown in the following figure. Assume that the ball does not slip when it strikes the ground and neglect the size of the ball and the impulse produced by the weight of the ball. Use v1 18 m/s, v2 = 3 m/s,01 = 51° and 02 = 14°. V2 V1 01 02 Determine the magnitude of the impulse the ground experts on the ball. Insert your answer in Ns correct up to at least a third decimal place.
2. Block 1 of mass m, slides from rest along a frictionless ramp from height h = 1.60 m and then collides (completely inelasticly) with stationary block 2 of mass m2 = 3.00 m.. After the collision, the two blocks slide into a region where the coefficient of kinetic friction is µx = 0.300 and come to a stop in distance d within that region. a) What is the speed of m, when it reaches the bottom of the ramp? b) What is the speed of the combination of the two blocks after the collision? c) What is the value of distance d?
The system is at rest with the spring unstretched when 8 = 0. The 4 kg particle is then given a slight nudge to the right. (@) If the system comes to momentary rest at e = 36", determine the spring constant k. (b) For the value k=110 N/m, find the total energy and speed of the particle when 8 = 20°. Neglect friction. h= 0.4 m
Q2: Sphere A collides with B as shown.
