Question

M=400г T=5 cек F=0.6H Vx=10m/c V0x=?

Answer 1

t=3c

m=0.4

F=0,6Н

v=10м/с

найти начальную скорость

из формуле Vx=Vo+a*t

а найдем из  F=m*a  ускорение   F/m =a  a=1.5

Vo= Vx - a*t     отсюда   Vo=10-1,5*5= 2,5 м/с

Answer 2

To solve for V0x, which represents the initial velocity in the x-direction, we can use the equation of motion:

Vx = V0x + (F * T) / M

Where: Vx = Final velocity in the x-direction (given as 10 m/s) V0x = Initial velocity in the x-direction (to be determined) F = Force applied (given as 0.6 N) T = Time duration (given as 5 seconds) M = Mass (given as 400 grams)

Note that we need to convert the mass from grams to kilograms to use it in the equation.

First, let's convert the mass to kilograms: M = 400 grams = 400 grams * (1 kilogram / 1000 grams) = 0.4 kilograms

Now, we can rearrange the equation to solve for V0x:

V0x = Vx - (F * T) / M

Substitute the given values:

V0x = 10 m/s - (0.6 N * 5 seconds) / 0.4 kg

Calculate the result:

V0x = 10 m/s - (3 N) / 0.4 kg

V0x = 10 m/s - 7.5 m/s ≈ 2.5 m/s

So, the initial velocity in the x-direction (V0x) is approximately 2.5 m/s.
