Answer:

0.01 m/s

Step-by-step explanation:

Velocity: This can be defined as the rate of change of displacement. Velocity is a vector quantity, because it can be represented both in magnitude and direction. The S.I unit of velocity is m/s.

Momentum: This is defined as the product of mass and the velocity of a body.

The S.I unit of momentum is kgm/s.

Mathematically, momentum can be expressed as,

M = mv............................. Equation 1

Where M = momentum of the SUV, m = mas of the SUV, v = velocity of the SUV.

making v the subject of the equation,

v = M/m......................... Equation 2

Given: M = 15 kgm/s, M = 1500 kg.

Substituting into equation 2,

v = 15/1500

v = 0.01 m/s.

Thus the velocity is 0.01 m/s
