Physics College Class Question: Uniform Accelerated Motion

1. An antelope moving with constant acceleration covers the distance between two points 90.0 m apart in 6.00s. Its speed as it passes the second point is 20.0 m/s. a) What is its speed at the first point? b) What is the acceleration?
2. The catapult of the aircraft carrier USS Abraham Lincoln accelerates an F/A – 18 Hornet jet fighter from rest to a take-off speed of 180 mi/h in a distance of 317 ft. Assume constant acceleration. a) Calculate the acceleration of the fighter in m/s2. b) Calculate the time required for the fighter to be accelerated to take-off speed.
3. An airplane travels 400m down the runway before taking off. If it starts from rest, moves with constant acceleration, and becomes airborne in 7.98 s, what is its speed in m/s, when takes off?

Physics High School Class Question: Could a camera capture a ghost?

No. Those are just aberrations.We cannot even see a ghost.

Physics of the Human Eye

For a near-sighted person we use concave lens
For a far-sighted person we use convex lens

What are your best memories in your physics class

I have a lot of memories in my physics class. The physics experiments, quizzes, my angry physics teacher. Every physics class I solve problems,learn from tutorials and fall asleep. I really love my physics course.
