You want to calculate the displacement of an object thrown over a bridge. using -10m/s^2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

given that acceleration due to gravity is a = -10 m/s^2

initial speed will be ZERO

and we need to find the displacement in t = 8 s

now we can use kinematics equation to find the displacement

now plug in all values in it

so it will displace downwards by 320 m

find the sum of the two horizontal vectors and the sum of the two vertical vectors
