Calculate the maximal friction force for a parked car between the rubber tires and a wet street. Assume the car’s mass is 1600 k
NikAS [45]

Answer:

Fr=12544N

Explanation:

1. Find the equation of eht maximal friction force:

The maximal friction force is given by the equation Fr=usmg, where μs is the static friction coefficient, m is the car´s mass and g is the gravitational force.

2. Replace values in the equation to find the answer:

Fr=0.8*1600kg*9.8\frac{m}{s^{2}}

Fr=12544N

Jody does long distance running and also strength trains twice a week.
murzikaleks [220]

<u>Answer:</u>

<em>Jody will have strong bones and show muscle hypertrophy. </em>

<u>Explanation:</u>

Long distance running practiced regularly helps in <em>increasing the strength of bones</em>. Muscular hypertrophy is the increase in mass of skeletal muscles due to the increase in the size of myofibrils or increase in muscle glycogen storage. <em>Strength training exercises</em> performed regularly induce muscular hypertrophy.

During strength <em>training exercises muscles</em> undergo contraction and repeated contraction breaks muscle fibres. New muscle fibres are added as a means of repair and this happens at the relaxing phase of muscles. More muscle fibres are added to <em>compensate the damage and thus muscle mass increases. </em>
