A) If a wind begins blowing from the southwest at a speed of 110km/h (average), calculate the velocity (magnitude) of the plane relative to the ground.
B) Calculate the velocity (direction) of the plane relative to the ground.
C) Calculate how far from its intenden posirtion will it be after 10 min if the pilot takes no corrective action.
Two stationary point charges of 4 nC and 2 nC are separated by a distance of 60 {rm cm}. An electron is released from rest at a point midway between the charges and moves along the line connecting them. What is the electric potential energy of the..
A stone with a mass of 0.700 is attached to one end of a string 0.8 long. The string will break if its tension exceeds 65.0 . The stone is whirled in a horizontal circle on a frictionless tabletop; the other end of the string remains fixed.
A 55kg pole vaulter running at 10m/s vaults over the bar. If the vaulter's horizontal component of velocity over the bar is 1.10m/s and air resistance is disregarded, how high was jump.
A liquid of refractive index 'n' is filled in a beaker of height 'h'. Find the amount by which a coin at its bottom seems to be raised.
Define the frequency components of an AM signal and draw the AM signal for the given modulation index.
A bumper car with mass m1 = 115kg is moving to the right with a velocity of v1 = 4 m/s. A second bumper car with mass m2 = 95 kg is moving to the left with a velocity of v2 = -3.7 m/s. The two cars have an elastic collision. Suppose the surface is fr..
An electron has an initial velocity of (15.0 j + 22.0 k) km/s and the constant acceleration of (3.00*10^12 m/s^22)i in a region in which uniform electric and magnetic fields are present. If B = (400 µT)i, find the electric field E.
A small block of mass m1 = 0.5kg slides to the left, with a velocity of v1 = -8.40 m/s, towards a curved wedge of mass m2 = 3 kg which sits on an icy, frictionless lake surface.
A 779-kg car stopped at an intersection is rear-ended by a 1820-kg truck moving with a speed of 15.0 m/s. If the car was in neutral and its brakes were off, so that the collision is approximately elastic, find out the final speed of both vehicles ..
A golf ball is hit at ground level. The ball is observed to reach its maximum height above ground level 3.8 s after being hit, How high is the fence
an 8.5 m long wire of resistance 20.6 \(\Omega\) carries a current of 6.6, What is the magnitude of the electric field in the wire
A lead ball is dropped into a lake from the diving board 30 m above the water. After entering the water, it sinks to the bottom with the constant velocity equal to velocity with which it hit the water. The ball reaches the bottom 10 s after it is ..
