Answer 1

Answer #1

6. When the ball is at the bottom, the centripetal force acts towards the center of the bowl i.e vertically upwards.

7. The net effect of Normal force and gravity is providing the centripetal acceleration

centripetal accelaration= Normal force (from the bowl wall) - force of gravity on the ball

An object with a mass, m = 5 kg, is released from rest at the top of the ramp. The length of the ramp is 2.3 m. The object slides down the ramp reaching a speed of 2.1 m/s at the bottom. a) If the friction force between the ramp and the object is 3 N, find the angle between the ramp and the horizontal theta (in degrees). b) What speed (in m/s) does the object reach at the bottom...
As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h.

As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h. When the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 15.0 cm that has a coefficient of kinetic friction μk = 0.520. Find h such that the block's speed after crossing the rough patch is 4.20 m/s. An object with a...

PLEASE SHOW WORK! A roller coaster starts from rest at a height h at the left side of a loop-the-loop, as shown in the figure. It is not attached to the track in anyway, and there is no friction from the track or from air resistance. If the radius of the loop is R = 6.0 m, what is the minimum height h for which the roller coaster will not fall off the track at the top of the loop?...
