kN

(b) When her speed reaches 1.2 m/s, she pulls in such a way thatshe and the platform go up at a constant speed. What force is sheexerting on the rope now? (Ignore the mass of the rope.)

At a lumberjack competition an axe with a mass of 1.25 kg is thrownat a target with a speed of 41 m/s. When it hits the target, itpenetrates to a depth of 0.055 m.
(a) What was the average force exerted by the target on theaxe?
1 N

(b) If the mass of the axe is halved, and the force exerted by thetarget on the axe remains the same, by what multiplicative factordoes the penetration depth change?
2
It doubles. It increases by a factor of the square root of two. Itdoes not change. It decreases by a factor of the square root oftwo. It halves.

Your firm is designing a new roller-coaster ride. The permitprocess requires the calculation of forces and accelerations atvarious important locations on the ride. Each roller-coaster carwill have a total mass (including passengers) of 800 kg and willtravel freely along the winding frictionless track shown in thefigure below. Points A, E, and G are on horizontal straightsections, all at the same height of 10 m above the ground. Point Cis at a height of 10 m above the ground on an inclined section ofslope angle 30°. Point B is at the crest of a hill, while point Dis at ground level at the bottom of a valley; the radius ofcurvature at both of these points is 20 m. Point F is at the middleof a banked horizontal curve with a radius of curvature of 35 m andat the same height as points A, E, and G. At point A the speed ofthe car is 11.1 m/s.

(a) If the car is just barely to make it over the hill at point B,what must be the height of point B above the ground?
__ m

(b) If the car is to just barely make it over the hill at point B,what should be the magnitude of the force exerted by the track onthe car at that point?
__kN

(c) What will be the acceleration of the car at point C?
__ m/s2

(d) What will be the magnitude and direction of the force exertedby the track on the car at point D?
__ kN directed 5 ---Select--- upward downward

(e) What will be the magnitude and direction of the force exertedby the track on the car at point F?
__ kN directed 7° upward from the horizontal.

(f) At point G a constant braking force is to be applied to thecar, bringing it to a halt in a distance of 30 m. What is themagnitude of this required braking force?
__ kN
