Q. A boat moves through the water of a river at 14 m/s relative to the water, regardless of the boat's direction. If the water in the river is flowing at 1.5 m/s, how long does it take the boat to make a round trip consisting of a 315 m displacement downstream followed by a 315 m displacement upstream?
Q. A small steel ball bearing with a mass of 23.0 g is on a short compressed spring. When aimed vertically and suddenly released, the spring sends the bearing to a height of 1.43 m. Calculate the horizontal distance the ball would travel if the same spring were aimed 32.0 deg from the horizontal.
When placed 1.2 m apart, the force each exerts on the other is 12 N and is repulsive. What is the charge on each? What if the force were attractive.
A particle with a charge of q = -5.10 nC is moving in a uniform magnetic field of vec{B}=( -1.24 T ) hat{z}. The magnetic force on particle is measured to be vec{F}= ( -7.60×10-7 N )hat{y}.
A 77 person stands on the uniform ladder 4.0 long, that weighs 100. The floor is rough; hence, it exerts both a normal force, and a frictional force, on the ladder. The wall, on the other hand, is frictionless; it exerts only the normal force.
Two horizontal forces, 249 N and 165 N, are exerted in opposite directions on a crate. What is the net horizontal force on the create? Be sure to point to the direction of the net force.
Coherent light with wavelength 610 passes through two very narrow slits, and the interference pattern is observed on a screen a distance of 3 from the slits. The first-order bright fringe is a distance of 4.84 from the center of the central bright..
A recording engineer works in a soundproofed room that is 45 dB quieter than the outside. If the sound intensity in the room is 1.30 x10-10 W/m2, what is the intensity outside.
When the front of the train passes the worker. A 1500 kg car moving north at 27.0 m/s is struck by a 2165-kg car moving east at 18.0 m/s. The cars are stuck together. How fast and in what direction do they move immediately after the collision.
a basketball player who is 2 m tall is standing on the floor 10 m from the basket. If he shoots the ball at a 40.0 degree angle with the horizontal, at what initial speed should he throw so that is goes through the hoop without striking the backbo..
A potential difference of 81 mV exists between the inner and outer surfaces of a cell membrane. The inner surface is negative relative to the outer surface. How much work is required to eject a positive sodium ion (Na+) from the interior of the ce..
Estimate the position of C.G or fulcrum & the masses of persons on a 16 feett sea saw, under balanced condition.
A 2.00-liter aluminum cylinder at 5°C is filled to the brim with gasoline at the same temperature. If the aluminum and gasoline are warmed to 59°C, how much gasoline spills out.
Find out the maximum torque on the wire. A bullet of mass 5g is fired horizontally into a wooden block of mass 1.26kg resting on a horizontal surface. The coefficient of kinetic friction between block and surface is 0.16.
