How far can a person run in 15 minutes if he or she runs at an average speed of 16 km/hr

Studentka2010 [4]

4 km/hr. There are four quarters in an hour, so just divide 16 by 4 and you get 4. It is directly proportional.

A 105 kg astronaut carrying a 16 kg tool bag finds himself separated from his spaceship by 18 m and moving away from the spacesh

Ratling [72]

Answer:

$T=22.5sec$

Explanation:

From the question we are told that:

Mass of astronaut $m_a=105kg$

Mass of tool $m_t=16kg$

Distance $d=18m$

Velocity of separation $v_s= 0.1m/s$

Velocity of tool bag $v_t=4.5m/s$

Generally the equation for momentum is mathematically given by

$P=mv$

Therefore

Initial Momentum before drop

$P_1=0.1(105+16)$

$P_1=12.1$

Initial Momentum after drop

$P_2=-16(4.5)+105V$

Therefore

Since $P_1=P_2$

$-72+105V=12.1$

$V=0.8m/s$

Generally the equation for Time T is mathematically given by

$T=\frac{d}{V}$

$T=\frac{18}{0.8}$

$T=22.5sec$
