A :-) F = ma
Given - m = 95 kg
a = 2.2 m/s^2
Solution -
F = ma
F = 95 x 2.2
F = 209

.:. The force is 209 N

How much force is needed to accelerate a 1,500 kg car at a rate of 7 m/s2?
Sidana [21]

Newton's 2nd law of motion:   

                       Force = (mass) x (acceleration)
                                         |                 |   
                                 (1,500 kg) x (7 m/s²)  =  10,500 newtons .

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.

When a ball is thrown straight up with no air resistance, the acceleration at its highest point. A) is upward B) is downward C)
Illusion [34]

Answer:

B) is downward

Explanation:

The acceleration is always downward, because it is the gravitational acceleration.

When the ball is going up the acceleration is opposing the movement, and when the ball is going down the velocity has the same direction as the acceleration

A proton travels with a speed of 5.02×10⁶ m/s in a direction that makes an angle of 60.0° with the direction of a magnetic ficld
Triss [41]

The magnitude of the magnetic force on the proton is 1.25× 10—¹³ N.

Speed of the proton = 5.02 × 10 ⁶ m /a

Angel of between the velocity and the magnetic force = 60 °

The magnitude of magnetic field B = 0.180 T

The magnitude of the magnetic force on the proton is,

F = q(v \times B)

F = qvB \: sin \:  θ

F = 1.6 \times 10 ^{ - 19}  \times 5.02 \times 10 ^{6}  \times 0.180 \times  \: sin \: 60°

= 1.25 \times 10 ^{ - 13}  \: N

Therefore, the magnitude of the magnetic force on the proton is 1.25× 10—¹³ N.
