Q. A glucose-winged gull, ascending straight upward at 5.20 m/s drops a shell when it is 12.5 m above ground.
(1) What is the magnitude and direction of the shell's acceleration just after it is released?
(2) Find out the maximum height above the ground reached by the shell.
(3) How long does it take for shell to reach the ground?
(4) What is the speed of the shell at this time?
In what direction should the pilot travel in this direct flight. Find out the distance she walks.
A converging lens has a focal length of f = 29 cm. If an object is placed 40 cm from the lens, where will the image be formed.
Calculate the magnetic field at the observation location. The space shuttle releases a satellite into the circular orbit 565 above the Earth. How fast must the shuttle be moving (relative to Earth) when the release occurs.
A car of mass 960 travels at a speed of 30 along the straight road. The driver sees a red traffic light ahead, and applies brakes. The coefficient of friction between the car tyres and the road is 0.88. Take the acceleration due to gravity to be 9.80..
Two point charges, q1= 2.40 nC and q2= -6.50 nC, are 0.100 m apart. Point A is midway between them; point B is 0.080 m from q1 and 0.060 m from q2 (see the attachment). Take the electric potential to be zero at infinity.
A train is travelling up a 4.5 degree incline at a speed of 3.25 m/s when the last car breaks free and begins to coast without friction. a) How long does it take for the last car to come to rest momentarily? b) How far did the last car travel befo..
Let the masses of blocks A and B be 4.0 kg and 2.0 kg, in that order, the moment of inertia of the wheel about its axis be 0.400 kg*m^2, and the radius of the wheel be 0.140 m. Find the linear accelerations of block A if there is no slipping between ..
Before throwing a 1.49 kg discus, an athlete rotates it along a circular path of radius 1.18 m. The maximum speed of the discus is 25.7 m/s.
What is magnitude of the linear acceleration of the hoop . Elucidate using Newton's Second Law of Motion, why you can throw a golf ball further than a bowling ball, still though you throw both at the similar angle and with the same amount of force.
Suppose one gallon of gasoline produces 1.1 multiplied by 108 J of energy, and this energy is enough to operate a particular car for 26 miles.
A ferry boat transports tourists among three islands. It sails from the first island to the second island, 4.7 km away, in a direction 37.0° north of east. It then sails from the second island to the third island in a direction 69.0° west of north..
The men's world record for the shot put, 23.12 m, was set by Randy Barnes of the United States on May 20; 1990.If the shot was launched from 6 ft above the ground at an initial angle of 42degrees, what was its initial speed.
