A small body moves forward along the OX axis. The body’s coordinate depends on time as x (t) = 2 + t-t^2, where t is expressed in seconds and the x – in meters. What is the projection of the acceleration of the body on the OX axis at time t = 1?
Answer. Posted on Saturday, April 11, 2015.
According to X(t)=Xi+Vi*t+a*t^2/2, the acceleration of the body will be -2 m/s^2. The acceleration is constant and is not depend on time.
