Sophie [7]

Answer:

initial magnitude will be 9 N and direction will be to the right

Explanation:

force= 9N

mass m= 330 grams

acceleartion = a

from newtons 2nd law of motion we write

$F= \frac{\mathrm{dP} }{\mathrm{d} t}$

dP is the chage in momentum dt is time taken and F is the Force applied

$9N= \frac{\mathrm{dP} }{\mathrm{d} t}$

this shows that the rate of change of momentum is 9 N

we also know that F= ma

putting values we get

$9= 0.330\times a$

a= 27.27 m/sec^2

The direction of acceleration will along the direction of force applied. So will be the direction of change momentum as in F=ma, mass is the scalar quantity and direction of force dictates the direction of motion. Hence, initial magnitude will be 9N and direction will be to the right

if you dropped a ball while standing on the surface of mars at what rate would it accelerate toward the ground

Inessa05 [86]

First of all you need to have in mind the following data:
<span>Mass of Mars: 6.43 x 10^23 kg
Radius of Mars: 3.40 x 10^6 m
Formulas: F = G(m1)(m2)/(r^2), m1 = F(r^2)/G(m2), m2 = F(r^2)/G(m1), F = ma G = 6.67 x 10^-11
</span><span> We can say that the first and second objects with mass can be called as following:
m1= centre of Mars
m2 = will be the ball.
</span>The distance between them = the radious of mars.
