A bungee jumper (m = 74.00 kg) tied to a 42.00 m cord, leaps off a 72.00 m tall bridge. He falls to 6.00 m above the water before the bungee cord pulls him back up. What size impulse is exerted on the bungee jumper while the cord stretches?
A ball of mass 1.024 g and positive charge q =40.3microC is suspended on a string of negligible mass in a uniform electric field. We observe that the ball hangs at an angle of theta=15.0o from the vertical. What is the magnitude of the electric field..
How several meters away is a cliff if an echo is heard 0.587 s after the original sound? Assume that sound traveled at 343 m/s on that day.
Two concentric hollow metal spheres have radii r1=1.50E-2 m and and r2=6.80E-2 m. At a point 9.80E-2 m from the center of the spheres, the electric field is directed outward and has a magnitude 2.08E+2 N/C. At a distance 5.80E-2 m from the center,..
A -11.0kg bucket is lowered vertically by a rope in which there is 163N of tension at a given instant, What is the acceleration of the bucket
If the bullet leaves the gun at a speed of 280 m/s, by how much will it miss the target? Illustrate at what angle should the gun be aimed so as to hit the target?
What is mass of the block of ice
The displacement of a particle moving under uniform acceleration is some function of elapsed time and acceleration. Suppose we write this displacement as: s=ka^mt^n where k is the dimensionless constant.
There are four coils of wire being used as electromagnets. They all have the equal size and are made up of the same material but have a different number of loops.
A mass m1 = 5.4 kg rests on a frictionless table and connected by a massless string to another mass m2 = 4 kg, How much work is done by the force F on the two block system
How are radioactive isotopes produced?
A little cat, Bella, walks in a straight line, which we shall call the x axis, with positive direction to the right. As an observant scientist, you make measurements of her motion and construct a graph of the little feline's velocity as a function..
The Achilles tendon inserts on the calcaneus at a distance of 8cm from the axis of the ankle joint. The force generated by the muscles attached to the Achilles tendon is 3000N, and the moment arm of this force is 5cm. a) Draw a free body diagram o..
