A 5.00 kilogram block slides along a horizontal,frictionless surface at 10.0 meters per second. for 4.00 seconds. The magnitude of the blocks momentum is ?
a. 200 Kg m/s
b. 50.0 Kg m/s
c. 20.0 Kg m/s
d. 12.5 Kg m/s
In this question a lot of information's are provided. Among the information's provided one information and that is the time of 4 seconds is not required for calculating the answer. Only the other information's are required. Mass of the block that is sliding = 5.00 kg Distance for which the block slides = 10 meters/second Then we already know that Momentum = Mass * Distance travelled = (5 * 10) Kg m/s = 50 kg m/s So the magnitude of the blocks momentum is 50 kg m/s. The correct option among all the given options is option "b".
