These are practice questions for Campbell's Biology, Chapter 42: Circulation and Gas Exchange. This is a great resource for AP, Honors,... Calculating acceleration of a braking car.

A 1.5 tonne car travelling at 100km/h suddenly brakes. The brakes provide an overall force of 50 times the normal reaction. Calculate the acceleration of the car. Finding velocity after a collision

On a very wet and slippery rugby field a 120 kg halfback tackles a 90 kg second rower. Prior to the collision the halfback is slipping with a velocity of 5.6m/s south and the second rower is sliding... Calculating impulse

A car of 1 tonne travels at a speed of 100km/h collides with a 3 tonne van travelling 20km/h in the same direction. After the collision the car rebounds at 20km/h. Calculate the impulse on the van... Calculating momentum, velocity, impulse and force.

A car (m=900kg) travelling at 70km/h hits a pedestrian (m=60kg) who is travelling at 1m/s in the same direction. After the collision the car has a velocity of 30km/h in the same direction it was originally... How does a microscope work?

How does a microscope work? What is the path of the light as it goes through a microscope? What is the purpose of each lens or prism? Please help. Osmosis - cell transport

Osmosis is the movement of water from an area of high concentration to an area of low concentration across a semi permeable membrane, but how does it link to the surrounding water being Hypertonic,...  Image 30k
