How fast would 40 Newtons of force accelerate a 2 kg object?

Physics
1 answer:
Digiron [165]3 years ago
8 0

Answer:

20 m/s^2

Explanation:

We can solve this problem by using Newton's second law of motion, which states that the net force acting on an object is equal to the product between its mass and its acceleration:

F=ma

where

F is the net force on the object

m is its mass

a is its acceleration

In this problem:

F = 40 N is the force on the object

m = 2 kg is its mass

Therefore, the acceleration of the object is

a=\frac{F}{m}=\frac{40}{2}=20 m/s^2

Explain Kepler's laws
cupoosta [38]
Kepler's three laws of planetary motion can be stated as follows: (1) All planets move about the Sun in elliptical orbits, having the Sun as one of the foci. (2) A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time.

An inclined plane of effective length 4.5m is used to raise a load of 500N through a height of 1.5m .If the list is raise by for
IrinaK [193]

Answer:

1850 N

Explanation:

The formula for friction force between the load and plane is given as ;

F= μ*N

N = mg cos θ

To find θ, which is the angle the inclined plane makes with the ground at the height of 1.5 m

Sin θ = 1.5/4.5

Sin θ = 0.3333

Sin⁻{0.3333} = 19.50°

θ = 19.50°

Finding N , where m= 500 N , and g= 9.81

N = mg cos θ

N= 500 * 9.81 * cos 19.50°

N= 4624 N

Coefficient of kinetic friction is calculated as;

μ=F/W

μ = 200/500 = 0.4

The magnitude of kinetic friction is given as;

Fk= μ * N

Fk = 0.4 * 4624

Fk= 1850 N

SCORPION-xisa [38]

Answer:

h = 120 m

h = 60 m

when rounded to two significant digits.

Explanation:

height of the higher ball drop point

h = ½gt² = ½(9.8)5.0² = 122.5 m

lower ball drop point

h = ½(9.8)(5.0 - 1.5)² = 60.025
