For a vector field 1-29 f a r cose a r2 sin0, find the flux of the vector f through (a) the upper (spherical) surface of a half-sphere of radius r, (r = r0< 0

How are calculation for velocity and speed different

A2000 kg car is rounding a curve of radius 200 m on a level road. the maximum frictional force the road can exert on the tires of the car is 4000 n. what is the highest speed at which the car can round the curve?

The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.
