Answer:
0.577
Explanation:
Answer:
Explanation:
Parameters given:
Angle = 30°
Mass of block = 5kg
Velocity = 6 m/s
Time = 4s
Frictional force is given in terms of Normal force as:
F = uN
Where u = coefficient of frictional force
N = normal force
Frictional force is given as:
F = mgsinθ
Normal force is given as:
N = mgcosθ
Coefficient of friction is therefore given as:
mgsinθ = u * mgcosθ
=> u = sinθ / cosθ
u = tanθ
u = tan(30°)
u = 0.577
