Consider the following steady, two-dimensional velocity field: V→=(u, v)=(a2−(b−cx)2)i→+(−2cby + 2c2xy)j→ Where are the stagnation points in this flow field?

The position of a crate sliding down a ramp is given by x=(0.05t^3) m, y=(1.7t^2) m, z=(6−0.85t^5/2) m, where t is in seconds. (a) determine the magnitude of the crate's velocity when t = 2 s. (b) determine the magnitude of the crate's acceleration when t = 2 s.

Which best represents the law of conservation of mass ?

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?
