Jane, looking for Tarzan, is running at top speed (5.2m/s ) and grabs a vine hanging vertically from a tall tree in the jungle.
How high can she swing upward?
what is the equation to solve this problem, i do not know how to approach it.
What is work done by the non-conservative force
Two balls are on a frictionless horizontal tabletop. Ball X initially moves at 10 meters per second, which angle and at what velocity will ball y move
Hooke's Law states that the force needed to stretch a spring is proportional to the amount the spring is stretched. If 10.0 N of force stretches a spring 4.00cm
A 200 lbs guy wants to slide down a plastic slide 24 ft long and on a 30 degree angle, after that the slide goes horizontally for 6 feet. Taking friction into consideration, how fast would he be going down the slide.
The velocity of an object falling in free fall increases with time. Does the acceleration also increase? Why or why not?
Most of us know intuitively that in a head-on collision between a large dump truck and a subcompact car, you are better off being in the truck than in the car. Why is this, find the average force on the truck driver from the seatbelt
A curve of radius 72m is banked for a design speed of 125km/h.If the coefficient of static friction is 0.34 (wet pavement), at what range of speeds can a car safely handle the curve
On vacation, your 1350 kg car pulls a 540 kg trailer away from a stop light with an acceleration of 2.15 m/s2. What force does the trailer exert on the car
The current in a resistor is given by I = (5.14) sin (70 pi t) when a voltage given by V = (180V) sin (70 pi t) is applied to it. What is the period of the voltage source
A spring stretches 0.150 when a 0.300 kg mass is hung from it. The spring is then stretched horizontally 0.100m from its equlibirum point and released. determine maximum acceleration of mass
Determine the magnitude and coordinate direction angles for the resultant force of the combination of the two forces shown.
A spring stiffness 900 N/m and relaxed length 1m stands vertically on a table. You hold a block of mass 1 kg barely touching the top of the spring. Assume you let the mass down onto the spring certain distance very slowly and view the mass is not mov..
