The answer is Hertz (Hz) named in honor of the German scientist Heinrich Hertz, who first conclusively proved the existence of electromagnetic waves.
Answer:
Force will be acting southward and the magnitude of force will be 1000 N
Explanation:
given,
mass of car = 1000 Kg
initial speed of the car (u) = 20 m/s
final speed of the car (v) = 0 m/s
distance to stop the car = 200 m
using equation of motion
v² = u² + 2 a s
0 = 20² + 2 x a x 200
400 a = -400
a = -1 m/s²
Now, we know
Force = mass x acceleration
F = 1000 x -1
F = -1000 N
- ve sign of force represent force will be acting in the opposite direction of motion.
Force will be acting southward and the magnitude of force will be 1000 N
