A 75kg person runs 3m/s off a cliff onto a vine that is 10m long. The person is perfectly positioned at the end of the vine. The vine is initially inclined at an angle of 37.0° with the vertical. What is the force called that the person applied to the vine? What is the magnitude of this force? What is the max height reached on the vine? Use the work-energy theorem .

Tarzan, who weighs 866 N, swings from a cliff at the end of a 16.0 m vine that hangs from a high tree limb and initially makes an angle of 24.3° with the vertical. Assume that an x axis points horizontally away from the cliff edge and a y axis extends upward. Immediately after Tarzan steps off the cliff, the tension in the vine is 789 N. Just then, what are (a) the force from the vine on Tarzan in...

________ In many cartoon shows, a character runs off a cliff, realizes his predicament, and lets out a scream. He continues to scream as he falls. If the physical situation is portrayed correctly, from the vantage point of an observer at the top of the cliff leaning over the edge, the pitch of the scream as he falls should be A) higher than the original pitch and constant. B) higher than the original pitch and increasing as he falls. C)...

Answer all please
In all problems, neglect air drag and use g- 10 m/s2 when needed. 1. A car initially moving at 30 m/s in a straight direction, reduces its speed to 10 m/s in a time of 10 seconds. Calculate the distance travelled by the car. 2. A cannon positioned on a flat, horizontal ground shoots a shell with muzzle speed of 180 m/s. Calculate the maximum height reached by the shell if (i) It is shot in a...
