Question 442971: A cat jumps off a chair 2ft off the ground with an initial velocity of 3ft/s. Use the formula below where t= time (in seconds), v= initial velocity, and h= initial height:
h=-16t%5E2%2Bvt%2Bs
A) Write an equation that gives the height (in feet) of the cat as a function of time (in seconds) since it jumps.
~For this part, I have: ~
0=-16t%5E2%2B3t%2B2
B) What is the height of the cat after 0.25 seconds?
~Did I do this right? I need help... ~
0.25=-16t%5E2%2B3t%2B2
I'm not sure what to do after this part. Thank for your help in advance. :D

A cat jumps off a chair 2ft off the ground with an initial velocity of 3ft/s. Use the formula below where t= time (in seconds), v= initial velocity, and h= initial height:
h%28t%29+=+-16t%5E2%2Bvt%2Bs
A) Write an equation that gives the height (in feet) of the cat as a function of time (in seconds) since it jumps.
h(t) =-16t^2+3t+2
B) What is the height of the cat after 0.25 seconds?
h(0.25) = -16(0.25)^2+3(0.25)+2
h(0.25) = -16(0.0625+0.75+2
h(0.25) = -1+2.75
h(0.25) = 1.75 ft
