When jumping straight down, you can be seriously injured if you land stiff-legged. One way to avoid injury is to bend your knees
nexus9112 [7]

(a) The man comes to a halt in 1.99 ms = 1.99 × 10⁻³ s, so his average acceleration slowing him from 6.33 m/s to a rest is

<em>a</em> = (6.33 m/s - 0) / (1.99 × 10⁻³ s) ≈ 3180 m/s²

so that the average net force on the man during the landing is

<em>F</em> = (70.8 kg) <em>a</em> ≈ 225,000 N

i.e. with magnitude 225,000 N.

(b) With knees bent, the man has an average acceleration of

<em>a</em> = (6.33 m/s - 0) / (0.147 s) ≈ 43.1 m/s²

and hence an average net force of

<em>F</em> = (70.8 kg) <em>a</em> ≈ 3050 N

(c) The net force on the man is

∑ <em>F</em> = <em>n</em> - <em>w</em> = <em>m a</em>

where

<em>n</em> = magnitude of the normal force, i.e. the force of the ground pushing up on the man

<em>w</em> = the man's weight, <em>m g</em> ≈ 694 N

<em>m</em> = the man's mass, 70.8 kg

<em>g</em> = mag. of the acceleration due to gravity, 9.80 m/s²

<em>a</em> = the man's acceleration

Using the acceleration in part (b), we have

<em>n</em> = <em>m g</em> + <em>m a</em> = <em>m</em> (<em>g</em> + <em>a</em>)

<em>n</em> = (70.8 kg) (9.80 m/s² + 43.1 m/s²) ≈ 3740 N

What type of circuit is it please give with explanation !!!!
Archy [21]
The circuit is a parallel circuit.

Because even one light bulb is broken, the others are still lit. Therefore it is not a series circuit

A rock from Mars experiences a 263% increase in its weight once it arrives on Earth. What accounts for this increase in weight?
leva [86]
The mass of Mars is smaller than that the mass of Earth, therefore the acceleration of gravity on Mars is much less than that the acceleration of gravity of the Earth.

 The weight of an object is directly proportional to the magnitude of the gravitational acceleration of the planet where it is.

 In this case, the gravitational acceleration in Mars is 3.711 m/s² and that of the planet Earth is 9.807 m/s².

 The acceleration of gravity on Earth is 2.63 times greater than that the acceleration of gravity on Mars. This explains that the same object weighs 263% more on earth

Kids are pelting a window with snowballs. On average, two snowballs of roughly 300-g mass hit the window each second, moving hor
hram777 [196]

Answer:

The average force exerted on the window due to two snowballs is 6 N

Explanation:

Given:

Mass of snowballs m = 300 \times 10^{-3} Kg

Velocity of snowball v = 10 \frac{m}{s}

For finding the average force,

Force is equal to the change in momentum,

   F = \frac{dP}{dt}

Here, final velocity is zero so we write,

 F = \frac{mv}{1}

Where dt = 1 sec

 F = 300 \times 10^{-30} \times 10

F = 3 N

Above value of force is due to one ball, but here given in question there are two ball,

F = 3 \times 2

F = 6 N

Therefore, the average force exerted on the window due to two snowballs is 6 N
