Question

Does anybody know about free fall for physics

Answer 1

Answer:

61.74 m/s

in short vf= 9.8m/s * 6.3 s

then u get 61.74

Explanation:

in Newtonian physics , free fall is any motion of a body where gravity is the only acceleration acting upon it . In the context of general relativity , where gravitation is reduced to a space - time curvature , a body in free fall has no force acting upon it.

thanks i hope it helped.

Answer 2

Answer: 61.74 m/s

Explanation: Use the first equation for free falling bodies

a = vf - vi / t

Derive for vf:

vf = at + vi ( vi = 0 since it starts from rest)

Substitute the values

vf = 9.8 m/s² x 6.3 s

= 61.74 m/s
