A bungee jumper undergoes simple harmonic motion with amplitude 4.6m and frequency 0.145Hz . Assume the bungee jumper follows the simple harmonic motion equation x=Acos(wt). Determine the bungee jumper's velocity at 0.25 s. Determine the bungee jumper's velocity at 0.50 s. Determine the bungee jumper's velocity at 1.0 s.
A 25.0g arrow is shot through a 7.8 cm apple. If the arrow enters the apple at 38.8 m/s and emerges with a speed of 30.10m/s in the same direction, what is the magnitude of force with which the apple has resisted the arrow.
What is height of the cliff
The 2.00 kg object below is released from rest at the height of 5.0 m on a curved frictionless ramp. At the foot of the ramp is a spring of force constant k = 450 N/m. The object slides down the ramp and into the spring, compressing it a distance x b..
Suppose I have two infinite wires, one on the y axis and one on the x axis, each charged uniformly with lamda C/m. Find an expression for the electric field E at any point in the x and y plane as a function of x and y.
