A person holds a gallon of milk with a mass of 3 kg away from their body so that their forearm is completely parallel with the ground. The length of the forearm is .38 meters. The biceps brachii attaches to the forearm 4 cm from the elbow at an angle of 60 deg. How much force must be exerted by the bicep in order to keep the forearm level while holding the milk

"322.5 N" is the appropriate solution.

Explanation:

The given values are:

Mass,

m = 3 kg

Length of forearm,

= .38 meters

Angle,

= 60°

As we know,

⇒  

⇒                      

On substituting the values, we get

⇒                          

⇒                          

⇒                          

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
