The mass of a high speed train is 4.5×105kg, and it is traveling forward at a velocity of 8.3×101m/s. given that momentum equals mass times velocity, determine the values of m and n when the momentum of the train (in kg⋅m/s) is written in scientific notation.

 The mass of the train is 4.5 x10⁵ kg.

The speed of the train is 8.3 x 10¹ m/s. 

 The momentum of the train is equal to mass times velocity.

P = m*v   

P = (4.5 x 10⁵ kg)(8.3 x 10¹ m/s)   

P= 3.7350 E 7 kg m/s

If we reduce the numbers of significant values

 P = 3.7 E 7 kg m/s

 m is equal to  3.7

 n is equal to 7.
