There are many ways to lose weight, but a sustainable plan generally involves behavior modification related to diet and exercise

. The best strategies involve adequate nutrition, regular physical activity, and practical ways to reduce calories while retaining important nutrients. Which of the following scenarios describes an individual using a strategy that will most likely help him or her achieve and maintain a healthful weight? Select all that apply.

The answer is adequate nutrition, regular physical activity, and practical ways to reduce calories while retaining important nutrients.

Explanation:

Despite that adequate nutrition, regular physical activity, and practical ways to reduce calories while retaining important nutrients is one of the best strategy to reducing weight, most time it is very difficult for those that want to reduce or control their weight to discipline themselves enough to follow these routine. But one an individual that want to loose weight or live a healthy lifestyle is able to follow these procedures he/she will surely loose weight.

Determine the launch speed of a horizontally launched projectile that lands 26.3m from the base of a 19.3m high cliff
mote1985 [20]

The launch speed of a horizontally launched projectile is 13.28 m/s.

<h3>Time of motion of the projectile</h3>

The time of motion is calculated as follows;

t = √(2h / g)

where;

  • h is height of the cliff
  • g is acceleration due to gravity

t = √(2 x 19.3 / 9.8)

t = 1.98 s

<h3>Launch speed of the projectile</h3>

X = Vxt

Vx = X/t

Vx = (26.3)/(1.98)

Vx = 13.28 m/s

Thus, the launch speed of a horizontally launched projectile is 13.28 m/s.

Two carts, one of mass 2m and one of mass m, approach each other with the same speed, v. When the carts collide, they
Svetradugi [14.3K]

Answer: Graph C is the correct option

Explanation:

The question is incomplete, please remember to submit the whole question :)

However, the rest of the question with its corresponding figures is below:

Assume that positive momentum is to the right, which of the following best represents the momentum of the cart of mass m as a function of time before and after the collision?

The initial momentum p_{o} of the cart with mass m (before the collision) is:

p_{o}=-mV (1) Note the negative sign indicates the direction of cart's velocity (to the left, as seen in the first image attached)

On the other hand, the final momentum p_{f} of both carts (after the inelastic collision) is:

p_{f}=(2m+m) V_{f}=3m V_{f} (2)

So, according to this, the correct graph tha best represents the situation is C. Since before the collision the momentum is negative, then both carts slow down after the collision (V_{f}), and taking into account the linear momentum is directly proportional to the velocity p_{f} (although is in the positive direction) is less than p_{o}.

What is the period of oscillation of a mass 40kg on a spring with constant k=10N/m?
iVinArrow [24]

The period of oscillation of the system is 12.56 s

Explanation:

The period of oscillation of a spring-mass system is given by

T=2\pi \sqrt{\frac{m}{k}}

where

m is the mass attached to the spring

k is the spring constant

For the system in this problem, we have

m = 40 kg

k = 10 N/m

Substituting into the equation, we find

T=2\pi \sqrt{\frac{40}{10}}=12.56 s
