ok so I have a question
At the instatn a race began, a 57-kg sprinter was found to exert a force of 80 N on the starting lbock at 22 degrees with respect to the ground
what was the horizontal acceleration of the sprinter?
I got roughly 1.3 s^-2 m
ok here's were i need some help
if the force was exerted for .34 s with what speed did the sprinter eave the starting block?
ok didn't he leave the starting block with an intial speed of zero?
by definition of accleration
a=t^-1 (V-Vo)
if theh Vo is not considered to be zero how to find the V and the Vo to fidn the acceleration
maybe there's another way to do this i do not know how to find the intial speed from the starting block
