Question

A 30-g car rolls from a hill 12 cm high and is traveling at 154 cm/s as it travels along a 275 cm horizontal track. What is the momentum of the car?
A. 360 g⋅cm
B. 1848 cm2/s
C. 4620 g⋅cm/s
D. 8250 g⋅cm

Answer 1

Answer:

Explanation:

By definition, the momentum is given by:

p=m*v

Where,

m: car mass

v: speed of the car

Substituting the values in the given definition we have:

p=3*154

Answer:

the momentum of the car is:

4620g * cm/s
