A golfer hits a shot to a green that is elevated 3.30 m above the point where the ball is struck. The ball leaves the club at a speed of 16.2 m/s at an angle of 49.0? above the horizontal. It rises to its maximum height and then falls down to the green. Ignoring air resistance, find the speed of the ball just before it lands.
What is the ratio of the amplitude of the damped oscillation
A resistor of 331 ohms is connected in series with a capacitor of 54.0 µF capacitance. what is the phase shift between the current and the voltage
At t=0 a grinding wheel has an angular velocity of 30.0 rad/s. It has a constant angular acceleration of 31.0 rad/s^2 until a circuit breaker trips at time t = 2.00 s. From then on, it turns through an angle 428 rad as it coasts to a stop at constant..
A 2.80-kg block starts from rest at the top of a 30.0° incline and slides a distance of 2.10 m down the incline in 1.20 s. Find the magnitude of the acceleration of the block.
find the ambulance's speed from these observations.
The intensity of the sound wave from a jet airplane as it is taking off is 85 W/m2 at a distance of 4.0 m. What is the intensity of the sound wave that reaches the ears of a person
A block of mass m1 = 1.75 kg and a block of mass m2 = 5.90 kg are connected by a massless string over a pulley in the shape of a solid disk having radius R = 0.250 m and mass M = 10.0 kg. These blocks are allowed to move on a fixed block-wedge of ..
A 1.7 kg block and a 2.3 kg block are attached to opposite ends of a light rope. Find the acceleration of the lighter block
A football of mass0.420 kg is thrown 60 m by a quarterback who imparts to it an initial velocity at an angle of 45 degrees above the horizontal. what force does his hand exert on the ball

Is it possible for both the pressure and volume of a monatomic ideal gas to change without causing the internal energy of the gas to change?
A string is wrapped around a disk of mass m = 1.7 kg and radius R = 0.08 m. Starting from rest, you pull the string with a constant force F = 7 N along a nearly frictionless surface. At the instant while the center of the disk has moved a distance..
