An object has a mass of 0.250 kg. What is the gravitational force of on the object by the earth?
sesenic [268]

Answer:

2.4525 N

Explanation:

The earths gravity is 9.81 N/Kg

And so to work this out you would multiply 9.81 by 0.250 which equals to 2.4525N

A force of 35 N acts on a ball for 0.2 s. If the ball is initially at rest:
olya-2409 [2.1K]

To solve this problem we will apply the concepts related to momentum and momentum on a body. Both are equivalent values but can be found through different expressions. The impulse is the product of the Force for time while the momentum is the product between the mass and the velocity. The result of these operations yields equivalent units.

PART A ) The Impulse  can be calculcated as follows

L= F\Delta t

Where,

F = Force

\Delta t =Change in time

Replacing,

L = (35N)(0.2s)

L= 7N\cdot s

PART B) At the same time the momentum follows the conservation of momentum where:

Initial momentum= Final momentum

And the change in momentum is equal to the Impulse, then

\Delta p = L

And

\Delta p = p_f - p_i

There is not initial momentum then

\Delta p = p_f

L = p_f

p_f = 7N\cdot s = 7kg\cdot m/s
