1/ santa loses footing and slides down a frictionless, snowy roof that is tilted at an angle of 45 degress. If santa sildes 10 m before reaching the edge, what is his speed as he leaves the roof?
Homework Answers
Santa's acceleration down the roof, a = 9.81*(cos45o) = 6.94 m/s2
Distance travelled down the roof, s = 10 m
Initial speed, u = 0
Speed as he leaves the roof, v = [u2 + 2as]1/2
=> v = [02 + (2 * 6.94 * 10)]1/2 = 11.78 m/s

A girl slides down a snowy hill on an inflated tube sled where she collides with a boy who is stationary in another tube sled. After the collision the girl moves off at an angle θ1 = 10 degrees from her original direction of motion and the boy moves off at an angle θ2 = 40 degrees. The girl and her sled have half the mass of the boy and his sled. After the collision, what is the ratio of...

d10 ocean Starting from rest, a penguin weighing 4kg, slides down a snowy incline at 66.8° to horizontal. The incline is 21.75m long (d 1 in diagram). Then the penguin slides along a long snow-covered horizontal section of length 18.8m (d2 in diagram), then off of a 33.18m tall cliff (h in diagram) into the ocean. The coefficient of friction between the penguin and all snowy surfaces is 0.266. Ignoring air drag, what is the penguin's speed when reaching the...

A girl slides down a snowy hill on an inflated tube sled where she collides with a boy who is stationary in another tube sled. After the collision the girl moves off at an angle theta 1 =0.35 radians from her original direction of motion and the girl moves off at 1.5 times the boy’s final speed . The girl and her sled have half the mass of the boy and his sled. At what angle theta 2 radians does...

A skier of mass
m started at rest and slides down over a
frictionless inclined plane. He reached the bottom at a speed of 20
m/s. Then reached the second inclined plan. If the second inclined
plane has a friction coefficient of 0.2 and inclined at angle of
20°. How far does he slide on it before coming momentarily to
rest?

An object released from rest slides down a frictionless ramp that makes an angle 0 of 70.00 with the horizontal. The object begins at a height H of 11.0 m above the base of the ramp. The bottom end of the ramp merges smoothly with a second frictionless ramp that rises at angle 02 of 35.0°. What distance d does the object slide along the second ramp before coming to a momentary stop? H e TH d= m When the...
