That depends on where the rocket is when it weighs 9800 Newtons.

If it's still sitting on the pad and hasn't launched yet, then its mass is 1000 kg.

If it has already blasted off and it's somewhere off the surface, then its mass is more than 1000 kg. The exact figure depends on how high it is off the surface when it weighs 9800 N.

8. John has to hit a bottle with a ball to win a prize. He throws a 0.4 kg ball with a velocity of 18 m/s. It hits a 0.2 kg bott

nasty-shy [4]

Answer: The ball is travelling with a speed of 5.5 m/s after hitting the bottle.

Explanation:

To calculate the speed of ball after the collision, we use the equation of law of conservation of momentum, which is given by:

$m_1u_1+m_2u_2=m_1v_1+m_2v_2$

where,

$m_1,u_1\text{ and }v_1$ are the mass, initial velocity and final velocity of ball.

$m_2,u_2\text{ and }v_2$ are the mass, initial velocity and final velocity of bottle.

We are given:

$m_1=0.4kg\\u_1=18m/s\\v_1=?m/s\\m_2=0.2kg\\u_2=0m/s\\v_2=25m/s$

Putting values in above equation, we get:

$(0.4\times 18)+(0.2\times 0)=(0.4\times v_1)+(0.2\times 25)\\\\v_1=5.5m/s$

Hence, the ball is travelling with a speed of 5.5 m/s after hitting the bottle.

Brut [27]

Answer:

The resultant vector is $\vec R = \vec A + \vec B = 7.196\,i + 6.464\,j$ .

Explanation:

First, each vector is determined in terms of absolute coordinates:

6-meter vector with direction: 30º north of east.

$\vec A = (6\,m)\cdot (\cos30^{\circ} \,i + \sin 30^{\circ}\,j)$

$\vec A = 5.196\,i + 3\,j$

4-meter vector with direction: 30º east of north.

$\vec B = (4\,m)\cdot (\cos 60^{\circ}\,i + \sin 60^{\circ}\,j)$

$\vec B = 2\,i + 3.464\,j$

The resultant vector is obtaining by sum of components:

$\vec R = \vec A + \vec B = 7.196\,i + 6.464\,j$

The resultant vector is $\vec R = \vec A + \vec B = 7.196\,i + 6.464\,j$ .
