175km per hour
That’s the speed it was going.
<u>The Weight </u>is a vector whose magnitude is the product of the mass m of the object and the magnitude of the local gravitational acceleration. Its always directed toward the center of the Earth.
- Mass=m=44.9kg
- Distance=s=20.5m
- initial velocity=u=0m/s
- Final velocity=v=62m/s
- Force=F
- Acceleration=a
Using third equation of kinematics
Apply Newton's second law
Answer:
Vectors have a size and a direction
vectors can have positive or negative values
Explanation:
Using Newtons Second Law:
F = m×a
F = (0.25 kg)(-2 m/s²)
F = -0.5 N
<h2>The correct option is C</h2>
