Horizontal motion has no effect on vertical motion. Gravity has the same effect on both balls' vertical motion ... they both accelerate downward at 9.8 m/s^2. (B)

Even more interesting: A bullet fired horizontally and another bullet DROPPED from the gun's muzzle at the same time both hit the ground at the same time ... Maybe miles apart, but their vertical motions are identical.

Starting from rest, a car travels 18 meters as it accelerates uniformly for 3.0 seconds. What is the magnitude of
omeli [17]

Answer:

a=4\frac{m}{s^2}

Explanation:

Hello.

In this case, for this uniformly accelerated motion in which the car starts from rest at 0 m/s and travels 18 m in 3.0 s, we can compute the acceleration by using the following equation:

x_f=x_0+v_0t+\frac{1}{2}at^2

Whereas the final distance is 18 m, the initial distance is 0 m, the initial velocity is 0 m/s and the time is 3.0 s, that is why the acceleration turns out:

a=\frac{2(x_f-v_ot)}{t^2} =\frac{2(18m-0m/s*3.0s)}{(3.0s)^2}\\ \\a=4\frac{m}{s^2}

Best regards.

Estefan has determined his BMI at 31. Explain how he can apply the FITT training principles to improve his body composition.
-BARSIC- [3]
Frequency:

Cardio : Five or more 
HIIT: 5 or 4

Strength: 2-3 days on non-consecutive days a week
 
Intensity:
How hard you work during the session

For cardio : workout at your target heart rate.
For HIIT: varying intensity from high to low or rest ( no slow pace)
For strength: you should lift enough weight to complete the needed number of reps and sets.

Time:

For cardio 30- 60 min
For HIIT 45 min (short periods of bursts followed by rest)

For strength depends on the amount of weight.

Type:

Either cardio, HIIT or strength training (resistance training) 

NOTE: This info is given by an unqualified brofessor, who uses his hard gained bro-science in the expense of scientific facts to solve others broblems.
