- help solve two part question A. A roller coaster begins at rest at the top of a 30 m hill. Find the velocity at a point 5 m above the bottom of the hill. B. A roller coaster begins at 6 m/s at the top of a 39 m hill. Find the velocity at a point 4 m above the bottom of the hill.You have put a sonar device at the top of a frictionless inclined plane, as shown in the diagram below. That device allows you to measure the distance an object is from the device, as well as the speed and the acceleration of that object. If we decide that the origin (h = 0) is at the sonar device, we want to know what the height change is as we slide down the incline. 0 For an angle below the horizontal of 6.46, we see that our object has slid a distance 1.13 m, as measured along the incline itself. Calculate the height change in meters - and report your answer as a negative number. (This value would be useful for calculating the change in gravitational potential energy, as we will do in the lab.) h=o 10% O i 26 QUATU 99+ hp X 55 83°F 3:11 PM 10/16/2022 Ctrl 0Hi, please can you help with the second question, I was able to do the first
- For safety reasons, some of the fastest dragsters, called top-fuel dragsters, do not race for more than 300 to 400 meters. Consider such a dragster that, when the light turns green, accelerates uniformly from rest and completes a 357 meter race in a time of 9.56 seconds. Part A: During this period, what is the dragsters acceleration expressed as a multiple of the acceleration due to gravity, g? Part B: If the dragster could continue with this average acceleration, what would its speed be, in miles per hour, after it has traveled a total distance of 1.6km, which is approximately one mile?A skier starts at the top of a 12º frictionless slope with a speed of 2.5 m/s. Her speed at the bottom is 15 m/s. Part A What is her acceleration on the slope? Part B What is the length of the slope? Part C How long does it take her to reach the bottom?I’m really just not sure how to type this into my calculator or even attempt to answer this question.
