Because oil is a lubricant which reduces friction between our hands and glass. Less friction and it tends to slip so yes , it is related to friction

Answer:
-12.38 N
Explanation:
This question requires you to first find the acceleration then apply Newton's 2nd law of motion to find the force.
To find deceleration use the formula;
v²= u²+2ad ---where
v= final speed = 0 m/s
u= initial speed = 3.0 m/s
a= acceleration { in this case , deceleration} = ?
d= distance from the point where its passenger rolled off= 4.0 m
therefore ;
Mass of the sled is calculated from its weight force.
Weight force = mg
mass of sled = weight force / g where g= 10 m/s²
mass of sled = 110/10 = 11kg
The magnitude of horizontal net force will be : F= ma where ;
m= mass of sled = 11 kg
a= deceleration = -9/8 m/s²
F = 11 * -9/8 = -12.38 N
Force is acting on the opposite direction of the initial motion of the sled.
Answer:
1.695 kg
Explanation:
maximum tension, T = 20 N
acceleration, a = 2 m/s^2
acceleration due to gravity, g = 9.8 m/s^2
Let the mass of fish is m.
Use Newton's second law
T - mg = ma
T = m (g + a)
20 = m (9.8 +2 )
m = 1.695 kg
Thus, the largest mass of the fish is 1.695 kg.
