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

Answer:

30 m/s

Explanation:

Velocity is $v_{final}=v_{initial}+at$ since we know that the initial velocity is 0, and the acceleration is $9.8 \frac{m}{s^2} \approx 10 \frac{m}{s^2}$ then we also know that time is 3 seconds it follows that: $v_{final}=v_{initial}+at=0+10\frac{m}{s^2}*3s=30\frac{m}{s}$

What us the formula of finding diameter

Over [174]

Answer:

The formula to find the diameter states the relationship between the diameter and the radius. The diameter is made up of two segments that are each a radius. Therefore, the formula is: Diameter = 2 * the measurement of the radius. You can abbreviate this formula as d=2r.
