find acceleration force divided by Mass
a=f/m
<span>h ( t) = h(1 sec) = -16t^2 + 541
so h (2 sec) = -16*(2)^2 + 541 = -64 + 541 = <span>477 ft
Therefore, </span></span>the height of the rock after 2 seconds is 477 feet.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
F=ma
for a Velocity/time
22/20
1.1
F=1.1. * 1100
F=1210newton
Octopus
1. Octopus/Squid. These similar creatures are both cephalopods and have three hearts in total, one systematic to go along with two “gill hearts” that force blood to the gills.
Hope This Helps! Have a Nice Day!!
