A roller-coaster car has a mass of 1000 kg when fully loaded with passengers. As the car passes over the top of a circular hill of radius23 m, its speed is not changing. (a) At the top of the hill, what is the normal force (using the negative sign for the downward direction)FN on the car from the track if the car's speed is v = 7.8 m/s? (b) What is FN if v = 20 m/s? Use g=9.81 m/s?.(a) Number!Units(b) NumberiUnits

Given data m=1000 kgr=23 mv=7.8 m/sg=9.81 m/s2 Here, m is the mass of the roller. r is the radius…

Planetary motion. A planet or asteroid orbits the Sun in an elliptical path'. The diagram shows two points of interest: point P, the perihelion, where the planet is nearest to the Sun, and the far point, or aphelion, at point A. At these two points (and only these two points), the velocity v of the planet is perpendicular to the corresponding "radius" vector ř, from the Sun to the planet. An arbitrary point Q is also shown.

Tom reached a speed of 29 m/s in the downhill skiing competition. Suppose he left the slope at that speed and then slid freely along a horizontal surface.

A parachutist whose mass is 90 kg drops from a helicopter hovering 1500 m above the ground and falls toward the ground under the influence of gravity. Assume that the force due to air resistance is proportional to the velocity of the parachutist, with the proportionality constant b₁ = 20 N-sec/m when the chute is closed and b₂ = 100 N-sec/m when the chute is open. If the chute does not open until the velocity of the parachutist reaches 35 m/sec, after how many seconds will the parachutist reach the ground? Assume that the acceleration due to gravity is 9.81 m/sec². The parachutist will reach the ground after (Round to two decimal places as needed.) seconds.
