Answer:
The force of static friction is 17.15 N
Explanation:
It is given that,
Mass of the bucket, m = 5 kg
The coefficient of static friction is, 
We need to find the maximum force of static friction. It is given by :


F = 17.15 N
So, the force of static friction is 17.15 N. Hence, this is the required solution.

Answer:

Given:
Initial speed (u) = 22 m/s
Final speed (v) = 0 m/s (Rest)
Time taken (t) = 4 seconds
To Find:
Distance travelled by car (s)
Explanation:
From equation of motion of object moving with uniform acceleration in straight line we have:

By substituting value of v, u & t in the equation we get:


Distance travelled by car (s) = 44 m
