Q. A rectangular barge 5.00 m long and 2.00m wide floats in fresh water a.) Find out how much deeper it floats while its load is a 400-kg horse. b.) if the barge can only be pushed 20-cm deeper into the water before water overflows to sink it, how various 400-kg horses can it carry?
A block of mass m is suspended from the string a height h above the ground. The string is wrapped around a disk shaped pulley with mass m and radius R. Find out the tension T in the string. (The answer should be in terms of variables). Rotational ..
define the potential difference between the plates.With what force must the player push the puck so that his force just equals the frictional force.
The collar C is moving downward with an acceleration of 1 m/s2. At the instant shown, it has a speed of 2 m/s which gives links CB and AB an angular velocity ωAB = ωCB = 10 rad/s. Determine the angular accelerations of CB and AB at this instant.
A person walks 36° north of east for 2.36 km. How far would another person walk due north and due east to arrive at the similar location.
compute the distance x the spring was compressed.
compute the total energy radiated by the Sun each second.
A 100 arrow is shot perpendicularly from a bow whose effective spring constant is 500. If the bow is drawn 75 before shooting the arrow, to what height does arrow rise.
The diagram on the left below shows two resistors in series with an ideal battery, in the diagram on the right; a third resistor has been added in parallel with R2. Calculating the resistance, current and potential difference.
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..
so hydrogen atoms have a thermal velocity of about 1000 m/s. How does the energy stored in the magnetic field compare with the kinetic energy in a given volume of space.
