I have a big homework due this tuesday, and I can’t do the 2 last questions 🙁
Here they are but I need to submit the Problem as an attachment, you need to see the pictures…
The deceleration of the mass centre G of a car during a crash test is measured by an accelerometer with the results shown, where the distance x moved by G after impact is 0.8m. Obtain a close approximation to the impact velocity v from the data given.
In an archery test, the acceleration of the arrow decreases linearly with distance s from the initial value of 4800m/s2 at A upon release to zero at B after a travel of 600mm. Calculate the maximum velocity v of the arrow.
