A horizontal force of 90.0 N is required to push a 75kg object along a horizontal surface at a constant speed. What is the magni
Varvara68 [4.7K]
If the object is moving at a constant speed, acceleration is 0. So:

F = ma

F = m\times 0

F = 0

The resultant force is 0. So the force pushing the object must be equal to the friction force acting, so 

Friction = 90 N

If a team pulls with a combined force of 4 newtons on an airplace with a mass of 36 kilograms,what is the acceleration of the ai
MatroZZZ [7]

Heya!!

For calculate aceleration, lets applicate second law of Newton:

                                                    \boxed{F=ma}

                                                 <u>Δ   Being   Δ</u>

                                                F = Force = 4 N

                                              m = mass = 36 kg

                                             a = Aceleration = ?

⇒ Let's replace according the formula:

\boxed{4\ N = 36\ kg * \textbf{a}}

⇒ Clear acceleration and resolve it:

\boxed{\textbf{a}=0,111\ m/s^{2}}}

Result:

The aceleration is of <u>0,111 meters per second squared (m/s²)</u>

Good Luck!!

Movies and TV shows sometimes portray a person being thrown backwards a sizable distance as a result of being struck by a bullet
MAXImum [283]

Answer:

 R = 4.24 x 10⁻⁴ m

Explanation:

given,

mass of the person = 60.3-kg

mass of the bullet = 10 gram = 0.01 Kg

velocity of bullet = 389 m/s

angle made with the horizontal = 45°

using conservation of momentum.

M v  + m u  = ( M + m ) V

60.3 x 0 + 0.01 x 389 = (60.3 + 0.01) V

V = \dfrac{3.89}{60.31}

V = \dfrac{3.89}{60.31}

V = 0.0645 m/s

for calculation of range

R = \dfrac{V^2sin 2 \theta}{g}

R = \dfrac{0.0645^2sin 2 (45^0)}{9.8}

     R = 4.24 x 10⁻⁴ m

the distance actor fall is  R = 4.24 x 10⁻⁴ m
