In a tonga, horse pulls a wagon. Which is the correct analysis of the situation?
The tonga moves forward because the horse pulls forward slightly harder on the wagon than the wagon pulls backward on the horse.
Because action always equals reaction, the horse cannot pull the wagon. The wagon pull backward just as hard as the horse pulls forward, there is no motion.
The horse's force on the wagon is as strong as the force of the wagon on the horse.
The horse can pull the wagon forward only if it weighs more than the wagon.
A vehicle is moving with speed $v$ on a curved road of radius $r$. The coefficient of friction between the vehicle and the road is $\mu$. The angle $\theta$ of banking needed is given by
A block of mass $m$ rests on a rough inclined plane. The coefficient of friction between the surface and the block is $\mu$. At what angle of inclination $\theta$ of the plane to the horizontal will the block just start to slide down the plane?
A coin placed on a rotating table just slips when it is placed at a distance of $1\,cm$ from the center. If the angular velocity of the table in halved, it will just slip when placed at a distance of from the centre $............\,cm$
A body of mass $\mathrm{m}$ is kept on a rough horizontal surface (coefficient of friction $=\mu$ ) A horizontal force is applied on the body, but it does not move. The resultant of normal reaction and the frictional force acting on the object is given by $\mathrm{F},$ where $\mathrm{F}$ is
