a body is moving in a straight line along x- axis Its distance from the origin is given by - Physics - Motion In A Straight Line

Question

a body is moving in a straight line along x- axis Its distance
from the origin is given by the equation x= 5t - t2, where x is in
m and t is in s find the average speed of the body in the interval
t=0 and t=2

x=5t - t2v = dx/dt = 5-2t average speed = ∫02vdt ∫02dt= ∫02(5-2t)dt ∫02dt=5t - t2202=(6/2) = 3m/s

a body is moving in a straight line along x- axis. Its distance from the origin is given by the equation x= 5t - t2, where x is in m and t is in s. find the average speed of the body in the interval t=0 and t=2
