A kilogram is a unit of mass and when multiplied by meters per second

amm1812

Answer:

it yields a derived unit known as Newton, which is the unit of Force.

Explanation:

The formula for force is given by Newton's Second Law, which states that whenever an unbalanced force is applied to a body, it produces an acceleration in the body in the direction of force.

$F = ma\\$

where, F = Force

m = mass

a = acceleration

Now, we substitute the respective S.I units of each quantity in equation:

F = Newton (N)

m = kilogram (kg)

a = acceleration = m/s²

Therefore,

$N = (kg)(m/s^2)$

So, it is clear from above expression that:

<u>When kilogram is multiplied by meter per second squared, it yields a derived unit known as Newton, which is the unit of Force.</u>

A team of astronauts is on a mission to land on and explore a large asteroid. In addition to collecting samples and performing e

sergij07 [2.7K]

Answer:

9.60 m/s

Explanation:

The escape speed of an object from the surface of a planet/asteroid is given by:

$v=\sqrt{\frac{2GM}{R}}$

where

G is the gravitational constant

M is the mass of the planet/asteroid

R is the radius of the planet/asteroid

In this problem we have

$\rho = 2.02\cdot 10^6 g/m^3$ is the density of the asteroid

$V=3.09\cdot 10^{12}m^3$ is the volume

So the mass of the asteroid is

$M=\rho V=(2.02\cdot 10^6 g/m^3)(3.09\cdot 10^{12} m^3)=6.24\cdot 10^{18} g=6.24\cdot 10^{15} kg$

The asteroid is approximately spherical, so its volume can be written as

$V=\frac{4}{3}\pi R^3$

where R is the radius. Solving for R,

$R=\sqrt[3]{\frac{3V}{4\pi}}=\sqrt[3]{\frac{3(3.09\cdot 10^{12} m^3)}{4\pi}}=9036 m$

Substituting M and R inside the formula of the escape speed, we find:

$v=\sqrt{\frac{2(6.67\cdot 10^{-11})(6.24\cdot 10^{15})}{(9036)}}=9.60 m/s$

A truck goes 5 m/s to 25 in 20 seconds. What is the acceleration of the truck during 20-seconds interval?

Aliun [14]

Acceleration = (change in speed) / (time for the change)

Change in speed = (ending speed) - (starting speed)

Change in speed = (25 m/s) - (5 m/s) = 20 m/s

Time for the change = 20 sec

Acceleration = (20 m/s) / (20 sec)

<em>Acceleration = 1 m/s²</em>

A child riding a bicycle at 5 meters per seconds accelerates at 2.0 meters per second for 4.0 seconds. What is the child's speed

slega [8]

Explanation:

Using Kinematics,

We have v = u + at.

=> v = (5m/s) + (2.0m/s²)(4.0s)

=> v = 13m/s.

Hence the child's speed is now 13m/s.
