trapecia [35]

Answer:

72 kg

Explanation:

The computation of the mass of the person is shown below:

As we know that

Water displaced weight = Raft weight + person weight

P_w.V = M_r + M_p

where

P_w denotes the water density i.e. 1000 kg/m^3

V denotes the volume of the water in m^3

Now

1000 × 0.224 = 152 + M_p

M_p = 224 - 152

= 72 kg

asambeis [7]

Answer:

4 N to the right

Explanation:

For the object in this problem, we have 2 forces acting on it:

- A force of 2 N, to the right

- A force of 2 N, to the right

The two forces are in line: this means that the two vectors can be simply added by calculating their algebraic sum.

If we take right as positive direction, the two forces can be written as

F1 = +2 N

F2 = +2 N

So, the net force will be

F=F_1+F_2=+2+2=+4 N

And the positive sign means the direction is to the right.

Phantasy [73]

Force equals mass time acceleration. Weight is a force and it can replace force in the equation. The acceleration would be gravity, which is an acceleration.

1.)

Fw (weight) = m (mass) · g (gravity, 9.8 m/s²)

Fw = m * 9.81 m/s²

560N = m · 9.81 m/s²

m ≈ 57.08 kg

2.)

d = 350 meters

t = 65 seconds

velocity = d/t

velocity = 350 meters / 65 seconds

velocity ≈ 5.38 meters/sec

3.)

Force = 35N

Distance = 2 meters

Work = Force · Distance

Work = 35N · 2 meters

Work = 70 J
