A Particle moves along the x-axis according to the expression x = 3t2 – 2t. Where x is in m and t is in s (a) What is the displacement of the particle in the time intervals t = 0 to t = 1 s and t = 1 s to t = 4 s?
(b) Calculate the average velocity for the time interval in (a). (c) Find the instantaneous velocity of the particle at t = 3 sec.

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!

explanation:

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
