The speed of a point on a rotating turntable, which is 0.172 m from the center, changes at a constant rate from rest to 0.531 m/s in 2.19 s. At t1 = 1.9 s, find the magnitude of the tangential acceleration. Answer in units of m/s2.

A train slows down at a constant rate as it rounds a sharp circular horizontal turn. Its initial speed is not known. It takes 19.8 s to slow down from 81 km/h to 37 km/h. The radius of the curve is 164 m. As the train goes around the turn, what is the mag...

A particle travels to the right at a constant rate of 6.5 m/s. It suddenly is given a vertical acceleration of 3.2 m/s2 for 3.9 s. What is its direction of travel after the acceleration with respect to the horizontal? Answer between −180 and +180. Answe...

At t1 = 1.9 s, find the magnitude of the total acceleration of the point. Answer in units of m/s2.

oh okay sorry I'm not the best at this and iv been super stuck >< thank you for the help

i also have to find this any hits or help is much appreciated. Find the centripetal acceleration of the electron. Answer in units of m/s2.
