Q. A 0.025kg golf ball moving at 23 m/s crashes through the window of a house in 2.0 10-4 s. After the crash, the ball continues in the equal direction with a speed of 10m/s. assume the force exerted on ball by the window was constant, what was magnitude of this force?
Q. A 5.7x10^2 kg hot-air balloon takes off from rest at the surface of the earth. The wind and lift forces take the balloon up, doing +9.7 x 10^4 J of work on the balloon in the procedure. At what height above the surface of the earth does the balloon have a speed of 7.50m/s?
A puddle holds 150 grams of water. If .50 grams of water evaporates from the surface, what is the approx temperature altering of the remaining water.
What would be the potential difference VC - VB across the thin resistor if the battery emf is 4.00 volts? Suppose that the electric field in the thick wires is very small (so that the potential differences along the thick wires are negligible)
In photo like the Hubble Deep Field, we see galaxies in many different stages of their lives. In general, which galaxies are seen in the earliest (youngest) stages of their lives.
Throughout a hard sneeze, your eyes may shut for 0.41 s. If you are driving a car at 98 km/h during such a sneeze, how far does the car move during that time.
Find out the speed of the satellite
What is the fundamental resonant frequency of the air column if the velocity of sound in the air is 340 m/s.
A 0.14 kg ball is placed in a shallow wedge with an opening angle of 126°. For each contact point between the wedge and the ball, determine the force exerted on the ball. Assume the system is frictionless.
Two charged Ping-Pong balls separated by the distance of 1.62 m exert an electric force of 0.0234N on each other. What will be the force if the objects are brought closer, to a separation of only 31.4 cm.
If a parallel mirror He-Ne laser had a homogeneous line shape with v=1.5GHz, and small signal peak coefficient of .001/cm length=100cm and reflectance's 100 percent and 97 percent, how many longitudinal modes would initially contribute to the laser o..
Two balls undergo a perfectly elastic head-on collision, with one ball initially at rest. If incoming ball has a speed of 200 m/s. What is the final speed of the incoming ball if it is much more massive than stationary ball.
As the block has raised a vertical height of 0.725, the tension in the cord is 4.66 .What is the velocity of the bullet originally.
