Answer:
14009. 72 kgms^-1
Explanation:
Momentum is the product of an objects mass and velocity
The calculated value of the magnitude of the car's momentum be 14006.72 kg.m/s or 68739 lb.mph.
What is momentum?Momentum is a property of a body moving in linear motion, It is product of mass and velocity. As velocity is a vector quantity, momentum is also a vector quantity with magnitude and direction. SI unit of momentum be kg.m/s.
Given parameters:
Mass of the car: m = 946.4 kg. = 2083 lb
Speed of the car: v = 14.8 m/s. = 33.0 mph
So, momentum of the car: p = mv = 946.4 × 14.8 kg.m/s = 14006.72 kg.m/s.
or p = mv = 2083 lb×33.0 mph = 68739 lb.mph.
Hence, the magnitude of its momentum be 14006.72 kg.m/s or 68739 lb.mph.
