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
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
