## Homework Statement

For my class we did a mini-lab that asked us to stand still and long jump. Kind of confused about how to solve because our teacher is horrible. I am supposed to calculate the vertical velocity at take off (which I thought was 0m/s but someone told me it's at the peak of the jump), the horizontal velocity of the takeoff, and the actual (resultant) velocity of the takeoff. I am supposed to calculate these values from the data I collected

displacement = 1.175 meters

time of flight = 0.49 seconds

I have some answers calculated trying to check them. Also supposed to get the angle of takeoff, but everyone in my class said that it is 45 degrees...

Thanks for taking your time to read this! Problem is for 10 extra points on our next test, well there will be a similar bonus question and I want to be able to understand how to do it correctly. Hopefully the values I collected will match some of the help I get. Thanks!

## Homework Equations

vf=(vi)+(a)(t)

vf^2=(vi)^2+(2)(a)(d)

d=(vi)(t)+(1/2)(a)(t^2)

## The Attempt at a Solution

vertical velocity at takeoff I got = 2.40 m/s

horizontal velocity at takeoff= 2.40 m/s

actual (resultant) velocity at takeoff= 3.39 m/s

angle of takeoff = 45 degrees
