### Learn more about Newton's second law of motion

The force being exerted on the 16-kg cart is 32N.

The force being exerted on the 16-kg cart can be determined using Newton's second law of motion, which states that force is equal to mass multiplied by acceleration. In the given graph, the cart is accelerating at a rate of 2 m/s2. Therefore, the force can be calculated as:

**force = mass x acceleration**

force = 16 kg x 2 m/s2 = **32 N**

**The 16-kg cart experiences a force of 32N, determined by applying Newton's second law of motion. According to this law, force equals mass multiplied by acceleration. In this scenario, the cart accelerates at a rate of 2 m/s². Substituting the values into the equation, the force exerted on the cart can be calculated as 16 kg multiplied by 2 m/s², resulting in a force of 32 N. This fundamental principle in physics establishes a quantitative relationship between force, mass, and acceleration. **

**Explanation:**

It is given that,

Mass of the passenger, m = 75 kg

Acceleration of the rocket,

**(a) The horizontal component of the force the seat exerts against his body is given by using Newton's second law of motion as :**

**F = m a**

F = 3675 N

Ratio,

So, the ratio between the horizontal force and the weight is 5 : 1.

**(b) The magnitude of total force the seat exerts against his body is F' i.e.**

**F' = 3747.7 N**

**The direction of force is calculated as :**

**Hence, this is the required solution.**

The horizontal component of the force the seat exerts against the passenger's body is 3675 N. The ratio of this force to the passenger's weight is 5. The total force the seat exerts has a **magnitude of 3793 N.**

(a) To calculate the horizontal component of the force the seat exerts against the passenger's body, we can use Newton's second law, which states that force is equal to mass times acceleration. In this case, the mass of the passenger is 75.0 kg and the acceleration of the rocket sled is 49.0 m/s2. So the force exerted by the seat is:

**Force = mass * acceleration**

Force = 75.0 kg * 49.0 m/s2

Force = 3675 N

Now let's compare this force to the passenger's weight. The weight of an object is given by the formula:

**Weight = mass * gravitational acceleration**

Weight = 75.0 kg * 9.8 m/s2

Weight = 735 N

To find the ratio, we divide the force exerted by the seat by the weight of the passenger:

**Ratio = Force / Weight**

Ratio = 3675 N / 735 N

Ratio = 5

(b) The total force the seat exerts against the passenger's body has both a horizontal and vertical component. The direction of the total force is the same as the direction of the acceleration of the rocket sled. The magnitude of the total force can be found using the Pythagorean theorem:

**Total Force = √(horizontal component****2**** + vertical component****2****)**

Total Force = √(36752 + 7352)

Total Force = 3793 N

**Answer:**

n = 1.6*10^9 capillaries

**Explanation:**

In order to calculate the number of capillaries, you take into account that the following relation must be accomplished:

** (1)**

A1: area of the aorta

v1: speed of the blood in the aorta = 40cm/s

n: number of capillaries = ?

A2: area of each capillary

v2: speed of the blood in each capillary

For the calculation of A1 and A2 you use the formula for the cross sectional area of a cylinder, that is, the area of a circle:

Where you have used the values of the radius for the aorta and the capillaries.

Next, you solve the equation (1) for n, and replace the values of all parameters:

**Then, the number of capillaries is 1.6*10^9**

**Answer:**

**Explanation:**

acceleration of test tube

= ω² R

= (2πn)² R

= 4π²n²R

n = no of rotation per second

= 3700 / 60

= 61.67

R = .10 m

acceleration

= 4π²n²R

= 4 x 3.14² x 61.67² x .10

= 14999 N Approx
