Answer:
Explanation:
m = Mass of object =
mg = Weight of object = 20 N
g = Acceleration due to gravity =
v = Final velocity = 15 m/s
u = Initial velocity = 0
d = Distance moved by the object = 150 m
= Angle of slope =
f = Force of friction
fd = Work done against friction
The force balance of the system is
The work done against friction is .
A
Velocity means speed with a direction. Unless the speed changes too, or it has an increase in speed, the answer would be different. Here, the direction changes, making the velocity change.
yeah its distance
Let's find the relationship
D. all answers are true
