A pick up van negotiates an unbanked curve of radius 40 m with a crate of eggs in the middle of its flat bed. If the coefficient of static friction between the crate and the truck, is 0.55 what is the maximum speed the van can take, so that the crate does not slide ?

1.	A pick up van negotiates an unbanked curve of radius 40 m with a crate of eggs in the middle of its flat bed. If the coefficient of static friction between the crate and the truck, is 0.55 what is the maximum speed the van can take, so that the crate does not slide ?
Answer» Solution :`r=40 m, MU = 0.55` Maximum speed = `v_("max") = ?` `v_("max") = sqrt(murg) = sqrt(0.55 XX 40 xx 9.8) = 14.68` m/s
