Oasis B is 6.0 km due east of oasis A. Starting from oasis A, a camel walks 24 km in a direction 15.0° south of east and then walks 30 km due north. If it is to then walk directly to B, (a) how far and (b) in what direction (relative to the positive x-axis within the range (-180°, 180°]) should it walk?
A 1.50 kg snowball is fired from a cliff 13.0 m high with an initial velocity of 14.0 m/s, directed 41.0° above the horizontal. If that gravitational potential energy is taken to be zero at the height of the cliff, what is its value when the snowbal..
