A block of mass m = 0.1 kg is released from rest at a height of h = 117 cm above the ground and slides without friction along the looped track, as can be seen in the figure. Part of the track is a circular loop of radius R = 20 cm. Calculate the normal force (in units of N) on the block exerted by the track at point A. (Take g = 10 m/s^2.) Answer:

Step 1
First, we need to find the initial potential energy of the block at the height h. The potential energy is given by the formula: PE = m * g * h Show more…

The block of mass $m$ sliding without friction along the looped track shown in Fig. $6-39$ is to remain on the track at all times, even at the very top of the loop of radius $r .$ (a) In terms of the given quantities, determine the minimum release height $h$ (as in Problem $40 ) .$ Next, if the actual release height is $2 h,$ calculate $(b)$ the normal force exerted by the track at the bottom of the loop, $(c)$ the normal force exerted by the track at the top of the loop, and $(d)$ the normal force exerted by the track after the block exits the loop onto the flat section.
1) A 2 kg mass slides without friction along the looped track shown in the figure. The mass is released from rest at a height of 4.2 m above the bottom of the loop, and the radius of the loop is 1.5 m. What is the downward (normal) force of the track on the mass when it's at the top of the track? (5 pts.)
