An airplane flies eastward and accelerates uniformly. At one position along its path it has a velocity of 26.7 m/s. It then flies a further distance of 49300 m and its velocity is 49.5 m/s. Find the airplane\'s acceleration and calculate how much time elapses while the airplane covers those 49300 m.
What is acceleration of an object sliding down to plane
A frictionless block of mass 1.95 is attached to an ideal spring with force constant 340 . At the spring is neither stretched nor compressed and the block is moving in negative direction at a speed of 12.6.
A plane mirror and the concave mirror (f = 8.70 cm) are facing each other and are separated by a distance of 23.0 cm. An object is placed between the mirrors and is 11.5 cm from each mirror.
Medical x rays are taken with electromagnetic waves having a wavelength around 0.104nm. What is the wave number of such waves
A 3500 kg block falls vertically through 5 m and then collides with a 400 kg pile, driving it 3.0 cm into bedrock. Assuming that the block-pile collision is completely inelastic, find out the magnitude of the average force on the pile from the bed..
