A jet plane has a takeoff speed of v = 74 m/s and can move along the runway at
an average acceleration of 1.4 m/s². If the length of the runway is 1.8 km, will
the plane be able to use this runway safely?
O Yes
No
A jet plane has a takeoff speed of Vto = 73 m/s and can move along the runway at an average acceleration of 1.5 m/s². If
the length of the runway is 1.7 km, will the plane be able to use this runway safely?
O Yes
No
Defend your answer.
The average person passes out at an acceleration of 7g (that is, seven times the gravitational acceleration on Earth). Suppose a car is designed to accelerate at this rate. How much time would be required for the car to accelerate from rest to 60.0 miles per hour? (The car would need rocket boosters!)
