Q. A 65-kg person wants to get to the top of a 2 m high ledge by swinging up to the top by running and grabbing a suspended rope suspended 5m above the ground by a tree. The acceleration due to gravity is 9.80m/s2. How fast must the person run in older to just make it to the top? At that speed, what is the initial tension in the rope as the person just leaves the ground (i.e., suppose the rope is still vertical, but the person is not touching ground)?
what is the horizontal distance x to the base. find the average net force exerted on him in the barrel of the cannon.
A 64 woman stands on a very light, rigid board that rests on the bathroom scale at each end. 1.5 m left of her and 2.0m total. what is the reading on each of the scales.
what volume should the balloon have after being inflated. Billiard ball A of mass mA=0.400kg moving with speed vA=1.80m/s strikes ball B, initially at rest of mass mB=0.500kg. As a result of collision, ball A is deflected off at an angle of 30.0 deg..
A person wearing a safety belt can withstand an acceleration of -3.0 x 10^2 m/s2. How thick must barriers be to safely stop a car that hits a barrier at 112 km/h.
Assume air resistance is negligible; from what height (in cm) above the compressed spring was the block dropped.
A candle is placed 16.0 cm in front of a convex mirror. When the convex mirror is replaced with a plane mirror, the image moves 7.5 cm farther away from the mirror. Find out the focal length of the convex mirror.
How much work is required to stretch the spring. A satellite is in a low circular orbit about the Eart.
A 51.0-g Super Ball traveling at 27.0 m/s bounces off a brick wall and rebounds at 21.5 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 3.75 ms,
In fact, the increased normal force at these large angles makes force of friction too large to move the lawnmower at all.
The wheel of a car has a radius of 0.365 m. The engine of the car applies a torque of 284 N · m to this wheel, which does not slip against the road surface. Since the wheel does not slip, the road should be applying a force of static friction to t..
A stone with a mass of 0.700 is attached to one end of a string 0.8 long. The string will break if its tension exceeds 65.0 . The stone is whirled in a horizontal circle on a frictionless tabletop; the other end of the string remains fixed.
A 1.35 kg object is moving in the x direction at 16.4 m/s. Just 3.61 s later, it is moving at 28.8 m/s at 36.0^circ to the x axis. What is the magnitude of force applied throughout this time.
