Question

A 1550 kg car located at < 319, 0, 0 > m has a momentum of < 45000, 0, 0 > kg·m/s. What is its location 10 s later? (Express your answer in vector form.)

Answer 1

< 45319, 0, 0 > m

Step-by-step explanation:

mass, m = 1550 kg

r = < 319, 0, 0 > m

v = < 4500, 0, 0 > m/s

t = 10 s

distance traveled in 10 second is

d = v x t

d = < 4500 x 10, 0 x 10, 0 x 10 > m

d = < 45000, 0, 0 > m

So, the new location of the car is

r' = r + d = < 319, 0, 0 > + < 45000, 0, 0 >

r' = < 45319, 0, 0 > m
