1) A pitched baseball of mass .200kg, arives at home plate with a speed of 40m/s and is batted straight back to the picture (at the same height) with a return speed of 60m/s. neglect air resistance and determine the work done by the bat on the ball
2) a 140kg astonaut (including space suit) aquires a speed of 2.50m/s by pushing off with his legs from an 1800kg space capsule.
A) what is the change in speed of the space capsule?
B) if the push last .500s what is the ave force exherted by each other?
A particle has a charge of -3.00 nC. A.) Find the magnitude and direction of the electric field due to this particle at a point 0.250 directly above it. B.) Upward or downward? C.) At what distance from the particle does its electric field have a ..
Three equal point charges, each with charge 1.95 , are placed at the vertices of an equilateral triangle whose sides are of length 0.400 . What is an electric potential energy of the system? (Take as zero the potential energy of the three charges ..
A 1.0--tall vertical tube is filled with 20o water. A tuning fork vibrating at 574 is held just over the top of the tube as the water is slowly drained from the bottom.
Two boxes A and B are connected to each end of a light vertical rope. A constant upward force 80.0 is applied to box. Starting from rest, box descends 10.4 in 3.40. The tension in the rope connecting the two boxes is 37.0
A muon is created at the top of Mount Nanga Parbat (height 8,100 m) and travels at constant speed to sea level, what is the height of Mount Nanga Parbat
The level of the liquid surface in the tank can be calculated. If the pressure on the gage is 20 kPa, Determine the depth d of liquid in the tank?
The diagram on the left below shows two resistors in series with an ideal battery, in the diagram on the right; a third resistor has been added in parallel with R2. Calculating the resistance, current and potential difference.
An electron is released from rest at the negative plate of a parallel plate capacitor. The charge per unit area on each plate is = 2.6 x 10-7 C/m2, the plates are separated by a distance of 1.4 x 10-2 m. How fast is the electron moving just before..
