Children slide down a friction-less water slide that ends at a height of 1.80 m above the pool. If a child starts from rest at p

Pachacha [2.7K]

Answer:

0.84 m

Explanation:

0.84 m

Explanation:

We are given that

Height,h=1.80 m

Horizontal distance,L=2.43 m

We have to determine the height h of the water slide.

Initial velocity,u=0

$t=\sqrt{\frac{2h}{g}}$

Where $g=9.8 m/s^2$

$t=\sqrt{\frac{2\times 1.8}{9.8}}=0.6 s$

$v=\frac{distance}{time}=\frac{2.43}{0.6}=4.05 m/s$

$h'=\frac{v^2}{2g}$

$h'=\frac{(4.05)^2}{2\times 9.8}$

$h'=0.84 m$

A machine gun fires 50gm bullets at a speed of 1000m/s. the Gunner, holding the machine gun in his hand,can exert an average for

horsena [70]

Answer:

We are given:

m = 50g OR 0.05 kg

v = 1000 m/s

Force applied by the gunner in a second = 180 N

Momentum(p) of the bullet:

p = mv

p = 0.05 * 1000

p = 50 kg m/s

Finding the recoil force:

The units kg m/s are also known as 'N' (newtons)

So, we can say that the force exerted on every bullet is 50 N

According to the law of conservation of momentum, every bullet fired applies a force of 50N towards the gunner

Hence, we can say that the recoil force of every bullet is 50N

Finding the number of bullets fired in a minute:

We are given that the gunner applied an average force of 180N on the gun

we know that that can also be written as 180 kg m/s. Notice the 's' in the units of the momentum, it tells us that this force is applied every second

So, to find the amount of force applied in a minute, we can multiply it by 60

Force applied by the gunner in a minute = (60 * 180) = 10800 N

Let n be the number of bullets fired in a minute

We can say that the force applied by the gunner is equal to the force applied by a bullet times the number of bullets fired

F(gunner) = n * F(bullet)

10800 = n * 50

n = 10800/50

n = 216 bullets / minute

The gunner shoots 216 bullets in a minute
