A mass of 10.0 kg is in a gravitational field of 3.50 N/kg. What force acts on the mass?

mash [69]

Answer:

Force=35 N

Explanation:

Given data

mass m=10.0 kg

Gravitational field E=3.50 N/kg

To find

Force

Solution

From definition of gravitational field intensity.

$E_{gravitational-field }=\frac{Force}{mass}\\ E=F/m\\F=mE\\F=(10.0 kg)*(3.50 N/kg)\\F=35N$

Which equations can be used to solve for acceleration? Select four options.

tatiyna

Explanation:

Acceleration of an object is calculated by finding the change in its velocity divided by time taken.

If $v_i$ is initial velocity, $v_f$ is final velocity and t is time taken. Then the acceleration of the object is given by :

$a=\dfrac{v_f-v_i}{t}\\\\at=v_f-v_i\\\\v_f=v_i+at$ .....(1)

So, the above equation is used to find acceleration. It is called the first equation of motion. After rearranging equation (1), the correct options are :

$t=\dfrac{\Delta v}{a}$

$v_i=v_f-at$

$v_f=v_i+at$

$a=\dfrac{\Delta v}{t}$

Answer:

mass= 60kg

velocity= 10m/s

momentum = mass × velocity

p=m×v

p= 60×10

p= 600kgm/s
