1) A boat is able to move through still water at 20m/s. It makes a round trip to a town 3.0 km
upstream. If the river flows at 5m/s, the time required for this round trip is:
2) A boat is traveling u
One day me and my friend were measuring each other to see how tall we were and her mom told us that measuring yourself with a tape measure doesnt give you your correct height. Is that true?-it is not
This is Calculus 1 material, rates of change (derivatives) more specifically. There are no actual values, so everything is to be done with variables, short of the numbers in the equation: V= pi*(r^2)*
A square loop of conducting wire is moved with a constant velocity v from a region of zero magnetic field into a region of uniform magnetic field and then out again into a field-free region. If the ar
A 13000-kg railroad car travels alone on a level frictionless track with a constant speed of 24.0 m/s. A 7450-kg load, initially at rest, is dropped onto the car.
What will be the cars new speed?

21)Slow Sam never wants to hurt anyone so he has only one bullet in his gun which instantly slows down at constant acceleration as it leaves the gun. If the bullet leaves the gun with an initial veloc
please its so confusing i just need a simple and precise explanation
thank you so much in advance-The rays of light going towards the ground are bent upwards again because the speed of light increase
there is an advanced idea called Quantum Mechanics that allows this but it is not easy to understand
Position is one quantity, Momentum or Mass times velocity is a different concept
the uncertainty
5. A boy throws a ball into the air as hard as he can and then runs as fast as he can under the ball in order to catch it. If his maximum speed in throwing the ball is 15 m/s and his best time for a 2
At an accident scene on a level road, investigators measure a cars skid mark to be 89 m long. The accident occurred on a rainy day, and the coefficient of kinetic friction was estimated to be 0.44.

my Physics teacher gave us data to graph on excel, he said he wanted acceleration and velocity graphs, but I cant figure out how to get the velocity graphs D:
the data was based on dropping differen
4. A pickup truck is accelerating from rest at a rate of 6m/s^2

During a physics experiment, a student pulls a rectangular conducting loop from between the poles of a magnet in 0.10s. The loop has an area of 8.0cm^2 and contains ten turns. Initially the entire loo
