Vector A has a magnitude of 71 units and points due west, while vector B has the same magnitude and points due south. Find the magnitude and direction of (a) A + B and (b) A - B . Specify the directions relative to due west.

A cart is driven by a large propeller or fan, which can accelerate or decelerate the cart. The cart starts out at the position x = 0 m, with an initial velocity of +6.4 m/s and a constant acceleration due to the fan. The direction to the right is positive...

A 48.0 kg child is stationary in the middle of an ice rink (no friction). A 0.750 kg football is thrown with a velocity of 21.2 m/s moving eastward. The child catches the ball and together they slide off in the eastward direction with a velocity of 0.326...

A piece of metal, when weighed in air, has a weight of 20.7 N. When completely submerged in blood (ĉ = 1060 kg/m3), the metal has a weight of 12.7 N. Based on the values from table 11.1 in the text, what is the most likely metal? Here is the answer but I...

A mass m = 0.068 kg of benzene vapor (Lv = 3.94x105 J/kg) at its boiling point of 80.1°C is to be condensed by mixing with water at 50.0°C. What is the minimum mass of water required to condense all of the benzene vapor? Assume the mixing and condensation...
