**Physics Problems on Motion and Acceleration**
1. **Problem 15**
- *Question*: An airplane travels 1000 ft at a constant acceleration while taking off. If it starts from rest, and takes off in 25.0 s, what is its takeoff velocity?
2. **Problem 17**
- *Question*: A car starts from rest and acquires a velocity of 20.0 mph in 10.0 s. Where is the car located and what is its velocity at 10.0, 15.0, 20.0, and 25.0 s?
3. **Problem 19**
- *Question*: An electron in a vacuum tube acquires a velocity of \(5.3 \times 10^8 \, \text{cm/s}\) in a distance of 0.25 cm. Find the acceleration of the electron.
4. **Problem 21**
- *Question*: An airplane has a touchdown velocity of 75.0 knots and comes to rest in 400 ft. What is the airplane's average deceleration? How long does it take the plane to stop? [0.869 knot = 1.47 ft/s]
5. **Problem 23**
- *Question*: The speedometer of a car reads 60.0 mph when the brakes are applied. The car comes to rest in 4.55 s. How far does the car travel before coming to rest?
6. **Problem 25**
- *Question*: A driver traveling at 25.0 mph sees the light turn red at the intersection. If her reaction time is 0.600 s, and the car can decelerate at \(18.0 \, \text{ft/s}^2\), find the stopping distance of the car. What would the stopping distance be if the car were moving at 50.0 mph?
**Note**: The problems listed involve calculations related to motion, using concepts such as velocity, acceleration, and deceleration in different scenarios. These exercises can help students understand and apply physics concepts to real-world situations.
