It momentarily comes to rest after attaining a height of 18m. How much energy is lost due to air friction? (g=10ms^−2)A pebble of mass 0.05 kg is thrown vertically upwards. Give the direction and magnitude of the net force on the pebble, (a) during its upward motion, (b) during its downward motion, (c) at the highest point where it is momentarily at rest. Do your answers change if the pebble was thrown at an angle of 45 degree with the horizontal direction? Ignore air resistance.Two balls of equal masses are thrown upwards, along the same vertical direction at an interval of 2 seconds, with the same initial velocity of 40m/s. Then these collide at a height of (Take g=10m/s^2).
