Vectors have a magnitude and direction whereas scalars only have a magnitude. The dot product of two vectors is a scalar.
Answer:
a. -191.7 J
Explanation:
The work done by a force is given by W = Fdcosθ where F = force applied and d = distance moved and θ is the angle between the force and distance moved.
Here, F = frictional force = 14.2 N
d = distance = 13.5 m
and θ = 180° since the direction of the frictional force and distance are opposite.
So, W = Fdcosθ = 14.2 × 13.5cos180° = -191.7 J
