A 160.0 g ball on a 70.7 cm long string is swung in a vertical circle about a point 184.0 cm above the floor. The string suddenly breaks when it is parallel to the ground and the ball is moving upward. The ball reaches a height 543.0 cm above the
A rock of mass 47 kg accidentally breaks loose from the edge of a cliff and falls straight down. The magnitude of the air resistance that opposes its downward motion is 252 N. What is the magnitude of the acceleration of the rock.
A sample of a gas in a cylindrical chamber with a movable piston occupied a volume of 4.626 liters when the pressure was 0.983 atm and the temperature was 27.2 °C. The pressure was readjusted to 1.388 atm by moving the piston. What was the vol
An electric dipole p makes an angle of 30° with a uniform electric field of magnitude 300 N/C. If the torque on the dipole is 3.00 × 10-12 N · m then calculate the magnitude of the dipole moment p.

In a coffee-cup calorimeter, 1.70 g of NH4NO3 is mixed with 79.0 g of water at an initial temperature of 25.00°C. After dissolution of the salt, the final temperature of the calorimeter contents is 23.67°C. Assuming the solution has a heat
A baseball is thrown at an angle of 28 degrees relative to the ground at a speed of 25.6m/s. The ball is caught 55.3841m from the thrower. The acceleration due to gravity is 9.81m/s square. How long is it in the air ?
Suppose a 64-kg boy and a 48-kg girl use a massless rope in a tug-of-war on an icy, resistance-free surface. If the acceleration of the girl toward the boy is 3.0 m/s2, find the magnitude of the acceleration of the boy toward the girl.
