A 64.0 kg person jumps from rest off a 13.0 m high tower straight down into the water. Neglect air resistance during the descent. She comes to rest 3.00 m under the surface of the water. Determine the average force that the water exerts on the diver. This force is nonconservative.
A particle undergoes a displacement Δr of magnitude 57 m in a direction 25° below the x axis. Express Δr in terms of the unit vectors x and y.
An insulated Thermos contains 150cm3 of hot coffee at 83°C. You put a 12g ice cube at its melting point to cool the coffee. By how many degrees has your coffee cooled once the ice has melted and equilibrium is reached? Treat the coffee as although..
A 4.5kg dog stands on an 18 kg flatboat at distance D = 6.10m from the shore. It walks 2.4 m along the boat toward shore and then stops. Assuming no friction between the boat and the water, find how far the dog is then from the shore.
An elastic cord is 69 cm long when a weight of 57 N hangs from it but is 70 cm long when the weight of 75 N hangs from it. What is the "spring" constant k of this elastic cord.
The potential difference between the plates of a capacitor is 145 V. Midway between the plates; a proton and an electron are released. The electron is released from rest.
From then on, the wheel turns through an angle of 431 rad as it coasts to a stop at constant angular deceleration. Illustrate a t what time does the wheel stop?
An astronaut on the Mars attaches a small brass ball to a 1.00- length of string and makes a simple pendulum. She times 13 complete swings in a time of 35.4 seconds. From this measurement she calculates the acceleration due to gravity on the Mars.
Suppose a 64.0 kg boy and a 48 kg girl use a massless rope in a tug-of-war on an icy, resistance-free surface. If the acceleration of the girl toward the boy is 3.00 m/s2, find out the magnitude of the acceleration of the boy toward the girl.
a car with a mass 1865 kg is travelling west and slows down uniformly to 8.5 m/s over a distance of 108 m. calculate the initial speed of the car if the required braking force is 7525 N
A fully loaded station wagon has a mass of 1690 kg. If each of its four tires is inflated to a gauge pressure of 211 kPa, what is the total tire area in contact with road.
A helicopter is ascending vertically with a speed of 5.20m/s. at a high of 125m above the earth, a package i dropped from a window. How much time does it take for the package to reach the ground? (Hint: the package's initial speed equals helicopte..
