A hammer falls from a construction worker's hand 30m above the ground at the same time that a filled soft drink can is projected

drek231 [11]

For harmer:-

initial velocity=u=0m/s

Acceleration due to gravity=10m/s^2

Now

$\\ \sf\longmapsto s=ut+\dfrac{1}{2}gt^2$

$\\ \sf\longmapsto s=0t+\dfrac{1}{2}(10)t^2$

$\\ \sf\longmapsto s=5t^2\dots(1)$

For soft drink:-

u=24m/s

$\\ \sf\longmapsto 30-s=(24)t+\dfrac{1}{2}(10)t^2$

Using eq(1)

$\\ \sf\longmapsto 30-5t^2=24t-5t^2$

$\\ \sf\longmapsto 24t=30$

$\\ \sf\longmapsto t=\dfrac{30}{24}$

$\\ \sf\longmapsto t=1.2s$

After 1.2s they will meet.

Now

putting t in eq(1)

$\\ \sf\longmapsto s=5t^2=5(1.2)^2=5(1.44)=7.2m$

At the height of 7.2m they will meet

A 75 kg football player is gliding forward across very smooth ice at 4.6 m/s. He throws a 0.47 kg football straight forward. A)

lord [1]

Answer:

4.53482 m/s

4.506 m/s

Explanation:

$m_1$ = Mass of player = 75 kg

$v_1$ = Initial velocity of player = 4.6 m/s

$m_2$ = Mass of ball = 0.47 kg

$v_1$ = Initial velocity of ball = 15 m/s

The linear momentum of the system is conserved

$(m_1+m_2)v_1=m_1v+m_2v_2\\\Rightarrow v=\dfrac{(m_1+m_2)v_1-m_2v_2}{m_1}\\\Rightarrow v=\dfrac{(75+0.47)4.6-0.47\times 15}{75}\\\Rightarrow v=4.53482\ m/s$

The player's speed is 4.53482 m/s

In the second case the equation of momentum is

$(m_1+m_2)v_1=m_1v+m_2(v_2+v_1)\\\Rightarrow v=\dfrac{(m_1+m_2)v_1-m_2(v_2+v_1)}{m_1}\\\Rightarrow v=\dfrac{(75+0.47)4.6-0.47\times (15+4.6)}{75}\\\Rightarrow v=4.506\ m/s$

The player's speed is 4.506 m/s
