On a snowy day a teen goes tobogganing. The teen pushes the tobbogan with an initial velocity of 1.0 m/s and it begins to slide down a bumpy hill as shown. If the height of the hill is 15 m what is the velocity of the toboggan at the bottom of said hill? Ignore friction.
Homework Answers
energy conservation
K.E. (INITIAL ) + P.E. (INITIAL ) = K.E. (FINAL)
(1/2) M U² + MgH = (1/2) MV²
(1/2 ) U² + gH = (1/2) V²
(0.5) (1)² + 9.8 ( 15) = (0.5) V²
0.5 + 147 = 0.5 V²
V² = 147.5 / 0.5 = 295
V = 17.175 m/s

A toboggan approaches a snowy hill moving at 10.9 m/s. The coefficients of static and kinetic friction between the snow and the toboggan are 0.50 and 0.35, respectively, and the hill slopes upward at 40.0 ∘ above the horizontal. A) Find the magnitude of the acceleration of the toboggan as it is going up the hill. B) What is the direction of the acceleration as the toboggan is going up the hill? C) Find the magnitude of the acceleration of...

On a rare snowy day in the Peach State, you and your friends decide to create a sledding run on a local hill near your home. You use an old plastic disk someone found in their garage as the sled and then use the winch motor on the front of someone's truck to pull people back up the hill. Answer the following questions using the following information: the hill makes an angle of 15 with the horizontal, the hill is...

Block A begins at the top of the track with an initial speed. It then slides on the track without friction going down to the bottom and back up to the second platform. Finally, it collides with a stationary block, B and the two stick together and continue to slide. Block A, with mass, mA= 0.75 kg is given an initial velocity, v0= 1.3 m/s. Block A slides without friction along a track downward from a platform at height h1=...

A car in an amusement park roller coaster ride rolls without friction at the top of a hill. The car begins at a height h from the top of a hill. A the bottom, the car then goes through a vertical loop where the car is upside down at the loop\'s top. If the radius of the loop is 20.0m, what is the minimum height h such that the car moves around the loop without falling off the track at...

A box is placed at the top of a ramp and begins to slide. The angles of the ramp is 30 degrees. The ramp is 40 meters long. If the box reaches a speed of 4 m/s at the bottom of the ramp, what is the coefficient of friction between the box and the ramp? Assume the initial velocity of the box is zero.
