Question
6. A small block slides down a frictionless track whose shape is described by y = (x^2) /d for x<0 and by y = -(x^2)/d for x>0. The value of d is 2.35 m, and x and y are measured in meters as usual. Suppose the block starts from rest on the track, at x = -2.36 m. What will the block s speed be when it reaches x = 0?

The power provided by a force can also be written as P = dW /dt = F · d7/dt = F .ö. A force F = (3i – 2j + 6k)N is applied to an object moving with a velocity i = (2î – 3k) m/s. a. What is the power provided by this force? Does the object speed up or slow down or neither, if this force is the only unbalanced force acting on the object? b. Consider a force that is always perpendicular to the velocity. Does the object speed up or slow down or neither, if this force is the only unbalanced force acting on the object?arrow_forward
