Answer:

Explanation:

The answer is 138.75 kgm/s

Impulse (I) is the multiplication of force (F) and time interval (Δt): I = F · Δt

It is given:

m = 0.25

F = 18,500 N = 18,500 kgm/s²

Δt = 0.0075 s

I = ?

I = F · Δt = 18,500 5kgm/s² * 0.0075 s = 18,500 * 0.0075 kgm/s² * s = 138.75 kgm/s

Ice wedging is brought about by ____.

grigory [225]

<span>Ice wedging is caused by water freezing and thawing. During this process of conversion of the water into ice the water is expanded and crack in the ground is formed. These cracks are formed duing the winter, when the water freezes, expands and the enlarges the cracks. In summer, when the ice melts more water is accumulated in the cracks and the process repeats.</span>

A friction force of 280 N exists between a cart and the path. If the force of reaction is 766 N, what is the minimum action forc

MatroZZZ [7]

force of friction on the cart is given as

$F_f = 280 N$

here we also know the reaction force due to surface

$R = 766 N$

so we can say reaction force is given as

$R = \sqrt{F_n^2 + F_f^2}$

$766 = \sqrt{F_n^2 + 280^2}$

$F_n^2 = 766^2 - 280^2$

$F_n = 713 N$

now by force balance we will say

$F_y + F_n = mg$

$F_y = mg - F_n$

$F_x = F_f$

also we know that

$F_f = \mu * F_n$

$280 = \mu * 713$

$\mu = 0.39$

now minimum force required to set this into motion

$F_{min} = \frac{\mu mg}{\sqrt{1 + \mu^2}}$

here we know that

$mg = F_n = 713 N$

$F_{min} = \frac{0.39* 713}{\sqrt{1 + 0.39^2}}$

$F_{min} = 259 N$

So it will require 259 N minimum force to move it
