A baseball with a mass of 0.152 kg is moving horizontally at 32.0 m/s [E], when it is struck by a bat for 0.00200 seconds. The velocity of the ball just after the collision is 52.0 m/s [W 20 degrees N].
a) Find the impulse experienced by the ball
b) Find the average net force of the ball
One mole of an ideal gas is heated so that T = AP2, where A is a constant and P is the pressure. The temperature changes from T0 to 4T0. Find out the work completed by the gas. (Use the following as necessary: T0, P0, and V0.)
We have pumped 20 bbls of fluid from the cement unit. But we think that we should have already achieved 425 psi at the unit. We are rigged up to do F.I.T and have already pressure tested all surface lines and there are no leaks.
Ricardo and Jane are standing under a tree in the middle of a pasture. An argument ensues, and they walk away in different directions. Ricardo walks 24.0 in a direction 60.0 west of north. Jane walks 12.0 in a direction 20.0 south of west. They then ..
A long horizontal wire carries a current of 48 {rm A}. A second wire, made of 2.6 mm diameter copper wire and parallel to the first, is kept in suspension magnetically 15 {rm cm} below. Examine the magnitude of the current in the lower wire.
The smallest insects that a bat can detect are approximately the size of one wavelength of the sound the bat makes. What is the minimum frequency of sound waves needed for the bat to detect an insect that is 0.53 cm long? (Assume the speed of soun..
At sea level, at latitude where, the pendulum that takes 2.00s for a complete swing back and forth has a length of 0.993m. What is the value of g in m/s2 at the location where the length of such a pendulum is 0.970m.
And if the plane could fly without this pilot, how much force would the plane require to maintain the equal acceleration?
A toy spacecraft is launched directly upward. When toy reaches its highest point, a spring is released and the toy splits into two parts with masses of .c2 kg and .08 kg.
A canoe has a velocity of 0.54m/s southeast relative to the earth. The canoe is on a river that is flowing at 0.52m/s east relative to earth.
At t = 0, a particle leaves the origin with a velocity of 12 m/s in the positive x direction and moves in the xy plane with a constant acceleration of (-2.0i+4j) . At the instant the y coordinate of the particle is 18 m, illustrate what is the x ..
What is the tension in the cord in the original situation. A cube of ice is taken from the freezer at -9.3°C and placed in a 95 g aluminum calorimeter filled with 297 g of water at room temperature of 20°C. The final situation is observed to be all..
