Some species of whales can dive to depths of 800m. What is the total pressure they experience at this depth?
(The density of sea water = 1020 kg/m, and 1 ATM=10$ N/m)
1.
A 15.0-kg object is pulled along a horizontal surface at a constant speed by a 25 N force acting at 30°
above the horizontal. How much work is done by this force as the object moves 10.0 m?
A force of F = 3i+ 0.5j – 5k), N is applied to a particle located at r =
Determine
2i +4k, m.
b) The angle between the vectors F and r
3.
a) The torque vector;
