Question

Transcribed Image Text:Use the following information to answer the next two questions
The year is 1927. You are a crime scene investigator.
You are considering pressing reckless driving charges
against the driver of Car 2. To do this, you must find
the speed of Car 2 before the crash. Allegedly, Car 1
was parked, when Car 2 crashed into it. Using the
skid pattern, you determine that the speed of the two
joined vehicles was 17 m/s immediately following the
impact. Car 1 has mass of 1800 kg and Car 2 has a
mass of 1100 kg.

Transcribed Image Text:1. The speed of the two cars (together) after the collision was 17 m/s. What was
that in km/h?
O 4.7 km/h
O 6.1 x 104 km/h
O 1.7 x 10-2 km/h
V 61 km/h
