A golfer hits a shot to a green that is elevated 3 m above the point where the ball is struck. The ball leaves the club at a speed of 13.9 m/s at an angle of 44.2° above the horizontal. It rises to its maximum height and then falls down to the green. Ignoring air resistance, discover the speed of the ball just before it lands.
Two bodies oscillate in SHM with the same amplitude (7.90 cm), Find the displacement of A when the displacement of B is 7.90 cm
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 4.7 e2 kg hot-air balloon takes off from rest at surface of the earth. The nonconservative wind and lift forces take the balloon up, doing +9.70 multiplied by 104J of work on the balloon in the process. At what height above the surface of the ea..
A diffraction grating with 610 lines per mm is illuminated with light of wavelength 520 nm. A very wide viewing screen is 2.1 m behind the grating. How many bright fringes can be seen on the screen
The rms speed of an oxygen molecule (O2) in a containerof oxygen gas is 700 m/s. What is the temperature of the gas
A boy kicks a soccer ball to the right. A graph of Force on the y axis and time on the x axis shows the force on the ball reaches 100N from time 0 - .1 s, What is its final speed of the ball before it hits the ground
An image of the moon is focused onto a screen using a converging lens of focal length (f= 34.3 centimeter). Evaluate the diameter of the moons image
The two blocks (m = 30 kg and M = 100 kg) in the figure below are not attached to each other. The coefficient of static friction between the blocks is µs = 0.49, but the surface beneath the larger block is frictionless.
What can you conclude about the resulting displacements?
