Well, now we seem to be back in the dark ages of some king's feet.
v1 = 42*5280/3600 ft/s
v2 = 58*5280/3600 ft/s
assuming constant acceleration we can use average v
va = 50*5280/3600 ft/s
so t = 660/va
a = (v2-v1)/t
v1 = 42*5280/3600 ft/s
v2 = 58*5280/3600 ft/s
assuming constant acceleration we can use average v
va = 50*5280/3600 ft/s
so t = 660/va
a = (v2-v1)/t
