use to answer 1 and 2. A truck driver slams on the brakes and skids to a stop through a displacement of x.
1.) if the truck's mass doubles, find the truck's skidding distance in terms of x.(hint:increasing the mass increases the normal force.)
2.) If the truck's initial velocity were halved, what would be the truck's skidding distance?
wudnt both of them be x/4 because if u increase the mass than the acceleration would decrease so the distance would decrease also and the only one less than x is x/4 and the same thing with initial velocity. if the ini. vel. is less than the acceleration would be less. but my teacher said that my answers were wrong. so please help.
