Jane needs to swing across a river filled with man-eating crocodiles in order to rescue Tarzan from danger. However, she must swing into a constant horizontal wind force, F, on a vine that is initially at an angle of ? with the vertical (see Fig. P5.73). Use these values to solve the problem: Jane's mass = 49.0 kg, Tarzan's mass = 80.0 kg, D = 50 m, F = 140 N, L = 40 m, ? = 24.6, and ? = 56.5°. With what minimum speed must Jane begin her swing in order to just make it to the other side? If she can make it to the other side with zero initial speed, what is her final speed (enter this value with a negative sign)?______ m/s Once the rescue is complete, Tarzan and Jane must swing back across the river. With what minimum speed must they begin their swing? If they can make it to the other side with zero initial speed, what is their final speed (enter this value with a negative sign)?______ m/s
Att = 0, force F-=(6.30i +6.10j +3.50k)N begins to act on a 2.90 kg particle with an initial speed of 3.60 m/s. What is the particle's speed when its displacement from the initial point is d = (1.60î + 2.80j + 7.80k) m ?
Hi I am in physics I, and they have the problem: In a baseball game, the 145g ball reaches the batter with a speed of 15.0m/s. The batter hits the ball with a force as shown in exact oppositie direction. The peak force (F max) is 1500N. Find the ball speed right after the hit. It was solved like: J= mvf - mvi area=1/2*b8h J= area = 1500(6)/2 + 1500(2)/2 J=6000 J=6.0 N*s 6.0 N*s = (0.1 +5kg)vf - (0.145kg)(-15) solve for vf vf=26.38 I really don't understand where 0.1 came from. If you can just break down i bit how this is solve that would be great. Thanks!
A boy who is, 73 kg, is training on Dagobah. He runs up a incline for 10 m with an average velocity of 6 mph. He then performs the same run with Yoda on his back in 4.31 s.

A 1.00×104 kg railroad car is rolling at 3.00 m/sm/s when a 6000 kg load of gravel is suddenly dropped in. What is the car's speed just after the gravel is loaded? Express your answer with the appropriate units(m/s).
Spectators watch a bicycle stunt rider travel off the end of a 57.5° ramp, rise to the top of her trajectory and, at that instant, suddenly push her bike horizontally away from her so that she falls vertically straight down, reaching the ground 0.525 s later. How far (in m) from the rider does the bicycle land if the rider has a mass mrider = 58.4 kg and the bike has a mass mbike = 14.5 kg? Neglect air resistance and assume the ground is level. ?m
To get up on the roof, a person (mass 70.0 kg) places 6.00-m aluminum ladder (mass 10.0 kg) against the house on a concrete pad with the base of ladder 2.00 m from the house. The ladder rests against a plastic rain gutter, which we can assume to frictionless. The center of ladder is 2.00 m from the bottom. The person is standing 3.00 m from the bottom. Find the normal reaction and friction forces on the ladder at its base.

A 0.400-kg blue bead slideson a frictionless, curvedwire, starting from rest atpoint Ⓐ in Figure P6.66,where h = 1.50 m. Atpoint Ⓑ, the bead collideselastically with a 0.600-kggreen bead at rest. Findthe maximum height thegreen bead rises as it movesup the wire.
A small rocket for gathering weather data has a mass of 30 kg and generates 1500 N of thrust. On a windy day, the wind exerts a 20 N horizontal force on the rocket. If the rocket is launched straight up, what is the shape of its trajectory, and by how much has it been deflected sideways when it reaches a height of 1.0 km? Because the rocket goes much higher than this, assume there’s no significant mass loss during the first 1.0 km of flight.
An object of mass m is suspended from the top of a cart by a string of length L as in Figure P5.88a. The cart and object are initially moving to the right at a constant speed 0. The cart comes to rest after colliding and sticking to a bumper, as in Figure P5.88b, and the suspended object swings through an angle . (a) Show that the initial speed is 0=2gL(1cos). (b) If L = 1.20 m and = 35.0, find the initial speed of the cart (Hint: The force exerted by the string on the object docs no work on the object.) Figure P5.88a
A ? = 20.0 [kg] block slides down a ? = 35.0◦ incline as shown, leaving the end with a speed of ?? = 1.10 [m/s]. At the same time, a ? = 70.0 [kg] cart, whose top end is located h = 2.00 [m] below the end of the chute, moves to the left with a speed of ?? = 2.00 [m/s], and catches the block as it falls. Once the cart catches the block, both move with the same speed. You may ignore friction. A. What is the speed of the block just as it hits the cart? B. What is the velocity of the block-cart system after the cart catches the block? C. What's the change in energy of the cart and block immediately before and immediately after the collision?
