Find the work done in joule by the force F= (-40 i+30 j) on a particle as the particle moves a displacement S = (-3i-9j) m. Answer:
To form a pendulum, a 0.092 kg ball is attached to one end of a rod of length 0.84 m and negligible mass, and the other end of the rod is mounted on a pivot. The rod is rotated until it is straight up, and then it is released from rest so that it swings down around the pivot. When the ball reaches its lowest point, what are (a) its speed and (b) the tension in the rod? Next, the rod is rotated until it is horizontal, and then it is again released from rest. (c) At what angle from the vertical does the tension in the rod equal the weight of the ball? (d) If the mass of the ball is increased, does the answer to (c) increase, decrease, or remain the same?

The fair is in town and one of the attractions is a bungee jump. They are trying to determine the safety restrictions to prevent an accident. The length of the cord is 6.3m. The maximum distance of the fall is H=31 m, and the spring constant is K=145N/m. Given this information, what is the largest mass of jumper this attraction can allow?
A toy car of mass m is pushed against a spring, compressing it a distance d from its natural rest length. The spring exerts a force F(x) = −(kx + ßx5)ix, where x is the displacement from its equilibrium position at the origin. The car is then released from rest and slides on a table with coefficient of friction µ. (i) What is the car's speed when it reaches the origin? (ii) If the car detaches from the spring when it reaches the origin, derive an equation that could be solved to find the location of the car when it comes to rest (do not solve).
