an owl m=4.72kg slides down a semi-circular ramp r=7.5m. the owl starts at the top ramp at rest. when the owl is at an angle 31.9. what is the normal force exerted by the owl.

Expert Solution

The situation can be visualized by

The total energy of the block at the top is

And the total energy at an angle θ is

The conservation of energy gives us

The centripetal force is given by

and for angle θ

The free-body diagram for the owl at the angle θ is

The force in the radial direction is given by

This force is responsible for the circular motion. So, this force must be equal to the centripetal force. i.e

Now putting the values in the equation

So, the normal force exerted by the circular surface on the owl is 25.3 N.

We know the normal forces come in pairs with equal magnitude and opposite in direction.

So, the normal force exerted by the owl is 25.3 N.

A mass m slides down a frictionless ramp and approaches a frictionless loop with radius R. There is a section of the track (between the ramp and the loop) with length 2R that has a kinetic friction coefficient of 0.5. From what height h must the mass be released to stay on the track? No figure. 1.5R 2.5R 3.5R 4.5R or 5.5R

A box (with a penguin inside) with mass, M, slides down a frictionless ramp, starting a height H above ground level. At the lowest point of the ramp (height = -0.1H) it slides through a curved section of track with radius, R= 0.25H. The box (w/ penguin) then rises to ground level (height = 0) and at that point, leaves a jump at an angle θ. At the highest point of its trajectory, h2, it strikes a blob of glue...

A block of mass m = 2.1 kg slides down a 36 ° inclined ramp that has a height h = 3.1 m. At the bottom, it hits a block of mass M = 7.1 kg that is at rest on a horizontal surface. Assume a smooth transition at the bottom of the ramp. If the collision is elastic and friction can be ignored, determine the distance the mass m will travel up the ramp after the collision.

A 0.25 kg block slides down a ramp that is 0.6 m tall, 0.8 m long and has a diagonal length of 1.0 m. The block starts at rest and arrives at the bottom with a speed of 1.3m/s. a.) How much heat was created by friction? b.)What is the average frictional force acting on the block? At what rate is kinetic energy being dissipated into heat near the bottom of the ramp? c.)Instead of a block, a cart with...

Beginning from rest, an object of mass 200 kg slides down a 9-m-long ramp. The ramp is inclined at an angle of 20o from the horizontal. Air resistance and friction between the object and the ramp are negligible. Let g = 9.81 m/s2. Determine the kinetic energy of the object, in kJ, and the velocity of the object, in m/s, at the bottom of the ramp.

A 2.2 kg cart slides eastward down a frictionless ramp from a height of 1.5 m and then onto a horizontal surface where it has a head-on elastic collision with a stationary 3.0 kg cart cushioned by an ideal Hooke’s Law spring. The maximum compression of the spring during the collision is 2.0 cm. [10 marks] a) Determine the velocity of the cart 1 just before the collision. [1 mark] b) At the point of maximum compression determine the velocity...
