Answer
given,
Car A weight = 1515 lb traveling eastward
Car B weight = 1125 lb traveling westward at a speed of 45 mph
distance to taken to stop the vehicle = 22.5 ft
1 ft = 0.000189394 mile
22.5 ft = 0.000189394 x 22.5 = 0.0043 mile
coefficient of friction = 0.750
Energy after the collision
using momentum conservation
Answer:
the path the object follows is called its trajectory so A. trajectory
Answer:
A
Explanation:
Contact force A contact force is any force that requires contact to occur. ... Contact forces are often decomposed into orthogonal components, one perpendicular to the surface (s) in contact called the normal force, and one parallel to the surface (s) in contact, called the friction force. In the Standard Model of modern physics, the four fundamental forces of nature are known to be non-contact forces.
