Q. A 200 weather rocket is loaded with 100 of fuel and fired straight up. It accelerates upward at 34 for 34 , then runs out of fuel. Ignore any air resistance effects. How long is the rocket in the air?
Q. A car travels along a straight line at a constant speed of 45.5 mi/h for a distance d and then another distance d in the same direction at another constant speed. The average velocity for the entire trip is 29.5 mi/h.
(a) What is the constant speed with which the car moved during the second distance d?
(b) Suppose the second distance d were traveled in the opposite direction; you forgot something and had to return home at the same constant speed as found in part (a). What is the average velocity for this trip?
(c) What is the average speed for this new trip?(c) What is the average speed for this new trip?
A baseball is hit at ground level. The ball reaches its maximum height above ground level 3.0 s after being hit. Then 2.5s after reaching its maximum height, ball barely clears a fence that is 97m from where it was hit. Suppose the ground is level..
A wire loop of radius 0.3 m lies so that an external magnetic field of magnitude 0.30T is perpendicular to the loop. The filed reverses its direction, and its magnitude changes to 0.20T in 1.5s. Find out the magnitude of the average induced emf in..
Find the force exerted by the plane on the pilot
A circular wire loop of radius 13cm carries a current of 3.66 A. It is placed so that the normal to its plane makes an angle of 34.8° with the uniform magnetic field of magnitude 9.70 T.
In each cycle of its operation, a refrigerator removes 10 J of heat from the inside of the refrigerator and releases 38 J of heat into the room. How much work per cycle is needed to operate this refrigerator.
There is a beam that weighs 1500 kilograms and is twenty meters in length. It has a 15000 kilogram mass on the right side, five meters from the center of gravity. obtain the net tension of each brace that is holding up the beam on both sides.
A 100g wire is held under a tension of 250N with one end at x = 0 and other x = 10m. At time t = 0, pulse 1 is sent along the wire from the end at x = 10 m. At time t = 30 ms, pulse 2 is sent along the wire from the x = 0. At what position x do the..
How long will a radar signal take to complete a round trip between earth and mars when the two planets are 0.7 AU apart.
Your projectile launching system is partially jammed. It can only launch objects with an initial vertical velocity of 42.0 m/s, though the horizontal component of the velocity can vary.
If the maximum acceleration the vehicle's brakes are capable of is -5 m/s2, what is the maximum reaction time of the motorist that would allow her or him to avoid hitting the deer.
