Formula for momentum is mass times velocity so you do 52 kg times 5 m/s and that equals 260 kg x m/s
120 volts for most home a phone charger can convert 120 volts ac to 5 volts dc
Technically, displacement is the "shortest" distance between any two points. If you say displacement is greater than distance, you will contradict the above statement. Displacement is always less than or equal to distance. Note that distance is a scalar whereas displacement is a vector. :)
