A bumblebee has a mass of 0.22 g. If its speed is 11.50 m/s, calculate its kinetic energy K E.

A wire with a linear mass density of 1.19 g/cm moves at a constant speed on a horizontal surface and the coefficient of kinetic friction between the wire and the surface is 0.250. If the wire carries a current of 1.

Using the definition of the scalar product, find the angle between the following vectors. (Find the smallest angle.) a) A = 5i - 9j and B = 5i - 5j (b) A = - 8i + 5j and B = 3i - 4j + 2k (c) A = - 2i + 2j and B = 3j + 4k
