A roller coaster car is near the bottom of its track, as shown in the figure. At this point, the normal force on the roller coaster is 3.5 times its weight. The speed of the roller coaster is 26 m/s. Determine the radius of the track's curvature

Bri is riding a roller coaster and encounters a loop. She is traveling 7.5 m/s at the top of the loop. The top of the loop has a radius of curvature of 3.9 m. Find the force that the loop exerted on Bri's 51 kg body at the top of the loop. Round your final answer to 1 decimal place.

The cylinder shown is rotating around its axis (the dashed line). If the cylinder is opened from the bottom find the minimum velocity needed for the cylinder to have such that the mass does not fall dovwn. (Radius of cylinder R-4 m, static friction coefficient between block and cylinder wall is u-0.98, M-4 kg). (Use g-9 8 ms 045 3.c5.5 block 5 C71

Hello, I have to record the least value of angle and maximum value of angle when block slides down hill based from my data.

Question: A) A car is driving too fast on a flat non-banked curve. The car cannot stay on the road. What path will the car take as it leaves the road? See Image. B) The driver wants to go faster around the same curve mentioned above and not run off the road. He adds sandbags to his car to make it weigh more so that the friction force between the tires and the road will be increased. Will this work? Explain your answer.
