The bullet lodges in the wood....
In the figure, a frictionless roller coaster car of mass m -828 kg tops the first hill with speed vo -17.0 m/s at height h 42.0 m. What is the speed of the car at (a) point A, (b) point B, and (c) point C? (d) How high will the car go on the last hill, which is too high for it to cross? Use g-10 m/s2 .4 lirst hill h/2
In the
figure, a frictionless roller coaster car of mass m = 637 kg tops the first
hill with speed v0 = 19.3 m/s at
height h = 37.2 m. How much work
does the gravitational force do on the car from that point
to (a) point A, (b) point B, and (c) point C? If the gravitational
potential energy of the car-Earth system is taken to be zero
at C, what is its value when
the car is at...

A roller coaster car of mass 800 kg when released from rest at
point A (height h above the ground) slides along the track and
inside the loop of radius 16.0 m. The car never loses contact with
the track.
A) Draw below a free body diagram for the car the car at the top
of the loop.
B) If the normal force acting on the car at the top is 1500 N,
what is the speed of the car...

3. A frictionless roller-coaster goes around a circular loop of radius 11 m. It enters the bottom of the loop going 32 m/s. Find the speed of the roller-coaster when it gets to the top of the loop 4. For the loop in the previous problem find the velocity of the roller-coaster as a function of height off the ground. Use that to find the centripetal acceleration as a function of height. Plot the centripetal acceleration as a function of...
