Physics Problems!!! Enjoy Physics!!!
1. An antelope moving with constant acceleration covers the distance between two points 80.0 m apart in 7.00s. 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 170 mi/h in a distance of 320 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 500m down the runway before taking off. If it starts from rest, moves with constant acceleration, and becomes airborne in 8.98 s, what is its speed in m/s, when takes off?
4. If a flea can jump straight up to a height of 0.525 m, what is its initial speed as it leaves the ground? b) For how much time is it in the air?
5. A player kicks a ball with a velocity of 42 m/s, 37ยบ from the horizontal. Find:
a. the maximum height the ball could reach.
b. the time to reach the maximum height.
c. the time the ball is in the air.
d. the range.
6. A car has a mass of 2000 kg. It is traveling at a velociyty of 15 m/s northward. A delivery truck with a mass of 3200 kg moving 18 m/s southward collided head-on with the delivery car. They stick together after collision. Find their common velocity after the collision.
7. A tricycle has a mass of 200 kg. If it has a velocity of 9 m/s northward, what is its momentum? If a car has a mass of 1800 kg, what should be its velocity to have the same momentum with the car.
