(8%) Problem 2: In a particular Cartesian coordinate system, the y and z-components of the acceleration are zero and the x-component varies
as given by the following function: a,(1) = 61 - 312 + 45e-UF, where t is in seconds, a, is in meters per square second, and the constant F is in
seconds. At t= 0, the particle was at positionx = 1 m with a velocity pointing towards the positive x-axis and having magnitude 35 m/s.
following problem you can take the constant F= 1.0 s.
