A bicycle initially moving with a velocity 50ms−1 accelerates for 5 s at a rate of 2ms−2. What will be its final velocity?
Two putty balls of equal mass moving with equal velocity in mutually perpendicular directions, stick together after collision. If the balls were initially moving with a velocity of 45√2 ms−1 each, the velocity of their combined mass after collision is
