the horizontal velocity would be equal to
Vh = sin (40) /60
= 0.74 * 60
= 44

the Vertical velocity would be equal to
<span>Vv = cos(40) * 60
=40</span>

A 17 kg box experiences an applied force of +175 N and a force of friction of -125 N. While experiencing these unbalanced forces

Flura [38]

Answer: (b)

Explanation:

Given

Mass of box $m=17\ kg$

Applied force $F=175\ N$

Friction force $f=-125\ N$

Box travels a distance of $s=15\ m$

time taken $t=5.25\ s$

Net unbalanced force $F_{net}=175-125=50\ N$

Work done by the unbalanced force

$\Rightarrow W=F_{un}\cdot s\\\Rightarrow W=50\times 15\\\Rightarrow W=750\ N$

Power developed by unbalanced force

$\Rightarrow P=\dfrac{W}{t}\\\\\Rightarrow P=\dfrac{750}{5.25}\\\\\Rightarrow P=142.85\approx 1423\ W$

Thus, option (b) is correct.

Why does the mass of a candle decrease after burning?

34kurt

Because when a candle burns the wax is burning off so as its heated more and more wax is lost and if more wax is lost... Obviously it means that the candles mass will be lower :)
