5. A 0.20-kg rocket in a fireworks display is launched from rest and follows an erratic flight path to reach the point P, as Figure shows. Point P is 29 m above the starting point. In the process, 425 J of work is done on the rocket by the nonconservative force generated by the burning propellant. Ignoring air resistance and the mass lost due to the burning propellant, find the speed vr of the rocket at the point P. 29 m To-0 mis

The figure(Figure 1) shows a 1.75-kg block at rest on a ramp of height h. When the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 10.0 cm that has a coefficient of kinetic friction 0.620. Part A Find h such that the block's speed after crossing the rough patch is 3.70 m/s να ΑΣφ h = m Submit Request Answer Provide Feedback Figure V Rough patch 10.0 cm
