A force F1 of magnitude 4.90 units acts at the origin in a direction 50.0° above the positive x axis. A second force F2 of magnitude 5.00 units acts at the origin in the direction of the positi
An alpha particle (a helium nucleus) is traveling along thepositive x-axis at 1250 m/s when it enters a cylindrical tube of radius 0.500 m centered on the x-axis. Inside the tube is a uniformelectri
A long, current-carrying solenoid with an air core has 1450 turns per meter of length and a radius of 0.0241 m. A coil of 146 turns is wrapped tightly around the outside of the solenoid. What is the
A thermos contains 155 cm3 of coffee at 85°C. To cool the coffee, you drop two 13 g ice cubes into the thermos. The ice cubes are initially at 0°C and melt completely. What is the final tem
A kayaker needs to paddle north across a 110-m-wide harbor. The tide is going out, creating a tidal current that flows to the east at 2.0 m/s. The kayaker can paddle with a speed of 3.4 m/s.
at what value of the distance d should a driver locate his car if he wishes to stay on a circular path without depending on friction?
A 95kg wood table is pulled with uniform velocity horizontally across a wood deck. how do you figure out the amount of force needed to start the table moving also how much force is needed to keep i
A car is traveling 72.0 km/h when the driver applies the brakes. if the car slows down uniformly with an acceleration of -4.5 m/s2, how far does the car travel before coming to rest?
What will be the equilibrium temperature when a 269 g block of copper at 277°C is placed in a 137 g aluminum calorimeter cup containing 829 g of water at 13.0°C?

Two forces, F1 and F2, act at a point. The magnitude of F1 is 2.00 N, and its direction is 60.0° above the x-axis in the second quadrant. The magnitude of F2 is 5.00 N, and its direction is 53.
A 2100 kg car moving east at 10.0 m/s collides with a 3000 kg car moving north. The cars stick together and move as a unit after the collision, at an angle of 35.0° north of east and at a speed
Suppose a car is traveling at 11.0 m/s, and the driver sees a traffic light turn red. After 0.590 s has elapsed (the reaction time), the driver applies the brakes, and the car decelerates at 6.00 m
