Answer:
im pretty sure thats called friction, or did you mean something else?
Answer: 8.81 J
Explanation: The scalar or dot product of 2 vector equals the product of the magnitude of both vectors and the cosine value of the angle between them
Magnitude of vector f (force) as given in the question = 12.5N
Magnitude of length = 0.75m
Angle between vectors = 25°
F. Δr = 12.5 * 0.75 * cos 25
F. Δr = 12.5 * 0.75 * 0.9063
F. Δr = 8.81 J
Answer:
The value
Explanation:
From the question we are told that
The weight of the sky diver is
The magnitude of the drag force is
The mass of the sky diver is
Generally the net force acting on the sky diver is mathematically represented as
Hence the acceleration of the sky diver is mathematically represented as
=>
=>
Answer:
Friction force always acts tangent to the surface at points of contact. Friction force acts opposite to the direction of motion. There are 2 types of friction: Static friction: If the two surfaces in contact do not move relative to each other, one has static friction.
