A 69 g particle is moving to the left at 25 m/s . How much net work must be done on the particle to cause it to move to the righ
LekaFEV [45]

Answer:11.59 J

Explanation:

Given

mass of Particle m=69 gm

Initially Particle moves towards left v_1=25 m/s

Final velocity of Particle is towards Right v_2=31 m/s

According to Work Energy theorem

Work done by all the Forces=change in Kinetic Energy

Work done by Force=\frac{mv_2^2}{2}-\frac{mv_1^2}{2}

W=\frac{69\times 10^{-3}}{2}\left [ 31^-25^2\right ]

W=\frac{69\times 10^{-3}}{2}\left [ 961-625\right ]

W=11.59 J

What are the 3 Laws of Newtonian Mechanics
Katyanochek1 [597]

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction

melisa1 [442]

Answer:

H_2 = 91.55 km

Explanation:

Gravity on the surface of planet is given as

g = \frac{GM}{R^2}

as we know that

M = 8.93 \times 10^{22} kg

R = 1821 km

now gravity on the planet is

g = \frac{(6.67 \times 10^{-11})(8.93 \times 10^{22})}{(1821 \times 10^3)^}

so we have

g = 1.8 m/s^2

now we know that

H_{max} = \frac{v^2}{2g}

so we will say

\frac{H_1}{H_2} = \frac{g_2}{g_1}

\frac{500}{H_2} = \frac{9.81}{1.8}

H_2 = 91.55 km

Please someone help me.
katovenus [111]

Answer:

acceleration of the car is 3 m\s^2

Explanation:

from rest means the initial velocity (vi) is zero

time = 5s

final velocity (vf) = 15m\s

a = vf - vi \ t

a = (15-0) \ 5

a= 3 m\s^2

which means that the car is speeding up 3 meters every second
