Question 22.
The centripetal acceleration of a car executing circular motion on a flat road can be described by ac=v2/r
If the friction with the road is suddenly half, then the centripetal acceleration must be half.
The velocity must reduce to})
Question 23.
Which part can't you do? Can you draw the labelled vector diagram?
The angle comes to 14.1 degrees.
