In summary, the conversation revolves around a stunt driver attempting to jump over eight cars using a horizontal ramp. To successfully clear the 20m distance and 1.5m height, the minimum speed needed is 36.2 m/s. When the ramp is tilted at a 10 degree angle, the new minimum speed can be found using a similar method to that of A. The question of finding the time it takes for the car to reach its maximum height is also brought up.

1. A stunt driver wants to make his car jump over eight cars parked side by side below a horizontal ramp. A.) With what minimum spped must he drive off the horizonal ramp? Vertical height of the ramp is 1.5 m above the cars, and the horizontal distance he must clear is 20 m
B.) If the ramp is now tilted upward so that takeoff angle is 10 degrees above the horizontal , what is the new minimum speed?



2.Used a lot of different ones.



3.I got 36.2 m/s for A.) but I can't find B.) at all.

Help please

What have you tried so far. If you can do A then B is very similar.

How much time will it take for the car to reach it's maximum height?
 

1. How is the minimum speed for a car jump calculated?

The minimum speed for a car jump is calculated by taking into account several factors such as the weight of the car, the distance of the jump, and the desired angle of the jump. A formula known as the "ramp jump formula" is often used, which takes into consideration the gravitational force, the angle of the ramp, and the height of the ramp. This formula can help determine the minimum speed required for a successful car jump.

2. What are the main factors that affect the minimum speed for a car jump?

The main factors that affect the minimum speed for a car jump include the weight and size of the car, the distance of the jump, the angle of the jump, and the condition of the ramp. These factors need to be carefully considered in order to calculate the minimum speed accurately.

3. How does the angle of the ramp affect the minimum speed for a car jump?

The angle of the ramp plays a crucial role in determining the minimum speed for a car jump. A steeper ramp will require a higher minimum speed in order to successfully clear the jump, while a shallower ramp will require a lower minimum speed. Adjusting the angle of the ramp can help fine-tune the minimum speed needed for a specific car jump.

4. What is the importance of calculating the minimum speed for a car jump?

Calculating the minimum speed for a car jump is crucial for the safety and success of the stunt. If the speed is too low, the car may not clear the jump and could result in a crash. On the other hand, if the speed is too high, it could lead to an unstable landing and potential injuries to the driver. Accurately calculating the minimum speed can help ensure a successful and safe car jump.

5. Are there any other factors that need to be considered for a car jump besides the minimum speed?

Yes, besides the minimum speed, there are other important factors that need to be considered for a car jump. These include the condition and design of the ramp, the landing area, and the driver's experience and skill. It is also important to have proper safety measures in place and to conduct thorough testing and preparations before attempting any car jump stunt.
