Answer:

Average speed, v = 1.66 km/h

Explanation:

It is given that, Ian walks 2 km to his best friend’s house, then walks 0.5 km to the library. He then makes a 2.5 km walk home.

Total time taken in the entire walk, t = 3 hours

We need to find the average speed of the Ian during his journey.

Total distance covered is, $d=d_1+d_2+d_3$

$d=2+0.5+2.5=5\ km$

Average velocity, $v=\dfrac{5\ km}{3\ h}=1.66\ km/h$

So, the average speed during the entire journey is 1.66 km/h. Hence, this is the required solution.

Two football players with mass 75 kg and 100 kg run directly toward each other with speeds of 6 m/s and 8 m/s respectively. if t

3241004551 [841]

heyaaaaa

Momentum before Pb = momentum after Pa

Pb = 75*6 - 100*8 = -350kgm/s = Pa = (75+100)V where V is the velocity of the combined mass of the two players after the collision.

Velocity has magnitude (speed) and direction. V = -350/175 = -2m/s

So the two players are moving at 2m/s in the direction the 100kg player was moving before the collision.

I arbitrarily chose the direction of the smaller player as positive so the opposite direction (of the larger player) had to be negative.

hope it helpssss!!!!!!

The truck in which

sertanlavr [38]

Answer:

m = 4

Explanation:

We have,

You apply a force of 600 N to the branch which acts as a lever. It means it is input force, IF = 600 N

The rear of the truck weighs 2,400 N. It means it is output force, OF = 2400 N

The ratio of output force to the input force is equal to the mechanical advantage of the lever arm. It is given by :

$m=\dfrac{2400}{600}\\\\m=4$

So, the mechanical gain of the lever arm is 4.
