#15000\ \text{kg m/s}#

Explanation:

Momentum #P# of elephant of mass #m=2000\ kg# & running at a speed of #v=7.5\ \text{m/s#

#P=mv#

#2000\cdot 7.5#

#=15000\ \text{kg m/s}#

Momentum #color(blue)(p = m * v = 2000 * 7.5 = 15,000# # kg. m.s^-1#

Explanation:

It's a term that describes a relationship between the mass and velocity of an object, and we can see this when it is written in equation form, p = mv, where p is momentum, m is mass in kg and v is velocity in m/s.

Because momentum is a vector quantity, this means it has both magnitude and direction.

Given #m = 2000 kg, v = 7.50 # #ms^-1#

Momentum #color(blue)(p = m * v = 2000 * 7.5 = 15,000# # kg. m.s^-1#
