A homeowner is trying to move a stubborn rock from his yard. By using a a metal rod as a lever arm and a fulcrum (or pivot point
Nonamiya [84]

Answer:

1.52 m

Explanation:

We are given that

Maximum force=F=679 N

Mass of rock ,m=385 kg

Distance,d=0.233 m

We have to find the  minimum total length L of the rod required to move the rock.

Torque on rock=T_1=mgd=385\times 9.8\times 0.233=879.11 N

Where g=9.8m/s^2

Torque on man=T_2=Force\times distance=(L-d)\times 679=(L-0.233)\times 679

T_1=T_2

(L-0.233)\times 679=879.11

L-0.233=\frac{879.11}{679}=1.29

L=1.29+0.233=1.523\approx 1.52 m

Hence, the minimum total  length of rod=1.52 m

. What is the velocity of a free-<br> falling object after 5 seconds?<br> (Use 10 m/s2 for gravity.)
Viefleur [7K]

Answer:

vf = 50 m/s

Explanation:

The equation for this kinematic problem is:

vf = vi + at

We are given:

a = 10m/s^2

vi = 0m/s

t = 5 sec

vf = ?

Solve for final velocity:

vf = 0 + 10(5)

vf = 50 m/s
