An oil rig in the gulf is held at its designated drilling location by 3 tugboats. tugboat A oulls with 42000 N straight in the east direction. Tugboat B pulls at an angle of 50 degrees north of west. tugboat C pulls 25 degress west of south. draw a proper free body diagram. find the magnitude of the tension of the ropes attached to tugboats B and C?
A person walks 36° north of east for 2.36 km. How far would another person walk due north and due east to arrive at the similar location.
What is the coefficient of kinetic friction
An 86 Kg person stands on a uniform ladder 4m long, that weighs 70N. The floor is rough; hence, it exerts both a normal force, and a frictional force, on ladder. The wall, on the other hand, is frictionless; it exerts only the normal force. What a..
Find out the critical angle for the glass-synthetic interface (same as for the glass-diamond interface). Sketch a picture of the incoming ray as it interacts will all subsequent interfaces.
A 1kg ball released from horizontal attatched to a 2.5 m string collides ellastically with a 2 kg block at rest. what is the speed of the block after the collision.
An artillery shell is fired with a minimal velocity of 470m/s at 50o above the horizontal. To clear an avalanche, it explodes on a mountain side 38 s after firing.
What is magnitude of the current
A fuel leak is discovered at this point, and crew calculates that the plane can safely fly no more than 170 km before an emergency landing should be attempted. The only appropriate location for an emergency landing is 100 km north of their current po..
An electron is at rest just above the surface of a sphere with the radius of 1.90 mm and a uniformly distributed positive charge of 2.1 x10-15 C.
Two particles with charges +6e and -2e are initially very far apart (effectively an infinite distance apart). They are then fixed at positions that are 4.92 x 10-10 m apart. What is EPEfinal - EPEinitial, which is the change in the electric potent..
A 2 kg ball is thrown straight up in the air. What is the net force acting on the ball when it reaches its maximum height?
The student throws a ball into the air along a path that he judges to make an initial angle of 59° with the horizontal and to be in line with the track. The student's professor, who is standing on the ground nearby, observes ball to rise verticall..
