Q. You make a slingshot from a 50cm long piece of rope in which you put a m=50g stone and you swing this rope in a circle over your head at the height of 2m above the ground at a rate of one revolution every 0.2seconds. When the stone leaves the sling it makes an angle of 25degrees above the horizontal. Suppose you are on level ground.
1) With what velocity does the stone leave the sling?2) How long is the stone in the air?3) What is the maximum height H reached by stone?4) What horizontal distance D does the stone travel before hitting the ground?5) Create a graph of x-position, x-velocity, and x-acceleration versus time and a graph of y-position, y-velocity, and y-acceleration versus time
what is the minimum coefficient of static friction required between tires and race track if the car is to stay on the track at a speed of 130m/s.
What is the magnitude
A hotel elevator ascends 110 {rm m} with a maximum speed of 4 {rm m/s}. Its acceleration and deceleration both have a magnitude of 1.20 {rm m/s^2}.
How much work must this force do to stop the wheel. An electron moving along the x axis has a position given by x = 11te-1t m, where t is in seconds. How far is an electron from the origin when it momentarily stops.
A 0.14 kg ball is placed in a shallow wedge with an opening angle of 126°. For each contact point between the wedge and the ball, determine the force exerted on the ball. Assume the system is frictionless.
A motorist drives south at 27.0 m/s for 3.90 min, then turns west and travels at 25.0 m/s for 2.40 min, and finally travels northwest at 40.0 m/s for 1.00 min. For this 6.40 min trip, find the values.
An extension cord made of two wires of diameter 0.129 {rm cm} (no. 16 copper wire) and of length 1.5 m (5 ft) is connected to an electric heater which draws 13.5 A on a 120-{rm V} line. How much power is dissipated in the cord.
Find the work done by this force on the particle and the final speed of the particle as it moves along a path.
A 20.0 kg wood ball hangs from a 1.3 m long wire. The maximum tension the wire can withstand without breaking is 300 N. A 0.70 kg projectile travelling horizontally hits and embeds itself in the wood ball.
An elevator cable can withstand a maximum tension of 19,500N before breaking. The elevator has a mass of 480 kg and a maximum acceleration of 2.24 m/s2. Engineering safety standards require that the cable tension never exceed two-thirds of the breaki..
A 11 g bullet is fired horizontally into a 109 g wooden block that is initially at rest on a frictionless horizontal surface and connected to a spring having spring constant 142 N/m. The bullet becomes embedded in the block.
If so how fast will the cars be traveling when they collided? If they did not, what is a distance between the cars at this point.
