At an air show, a jet plane has velocity components vx= 695km/h and v y =415km/h at time 4.35 s and v x =938km/h and V y =365km/h at time 7.52s.
A)For this time interval, find the xxx component of the plane's average acceleration.
b)For this time interval, find the yyy component of the plane's average acceleration.
C)For this time interval, find the magnitude of its average acceleration.
D)For this time interval, find the direction of its average acceleration.
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: ax(t) = 8t - 2t2 + 15e-t/F, where t is in seconds, ax is in meters per square second, and the constant F is in seconds. At t = 0, the particle was at position x = 3 m with a velocity pointing towards the positive x-axis and having magnitude 25 m/s. In the following problem you can take the constant F = 1.0 s.
