A traffic light weighing 100 N is supported by two ropes as shown in the figure. The tensions in the ropes are closest to  

A 6.00-kg block is in contact with a 4.00-kg block on a horizontal frictionless surface as shown in the figure. The 6.00-kg block is being pushed by a horizontal 20.0-N force as shown. What is the magnitude of the force that the 6.00-kg block exerts on the 4.00-kg block?  

Kira’s car enters a 300-m radius horizontal curve on a rainy day when the coefficient of static friction between its tires and the road is 0.600. What is the maximum speed at which this car can travel around this curve without sliding?  

Two objects having masses m1 and m2 are connected to each other as shown in the figure and are released from rest. There is no friction on the table surface or in the pulley. The masses of the pulley and the string connecting the objects are completely negligible. What must be true about the tension T in the string just after the objects are released?  

Prof. Hamilton is straining to lift a large crate, without success because it is too heavy.(Does he even lift?) We denote the forces on the crate as follows: P is the upward forcethe professor exerts on the crate, C is the vertical contact force (normal force) exerted on the crate bythe floor, and W is the weight of the crate. How are the magnitudes of these forcesrelated while the professor is trying unsuccessfully to lift the crate?(HINT: the crate has 0 acceleration in this situation)

A container ship is being pulled through the Suez Canal at constant velocity by two tugboats as shown in the figure. The lines attached to the two tugboats have the same tension of 200,000 N. Each line makes an angle of 28.0° with the direction the ship is being towed. What is the magnitude of the “frictional” force due to the water on the ship?  

Consider the table below which shows the probability of it raining for a set number of days in June in Seattle, WA. Use this information to answer the question that follows.  Probability Table Number of Days 0 1 2 3 4 5 6 7 Probability 0.1 0.2 0.05 0.15 0.08 0.37 0.02 0.03   What is the probability that it rains at least 3 days a month in June?

Consider the table below which shows the probability of a customer ordering a certain number of baked goods from a bakery.
