What is the equation for finding the acceleration of an object moving in a straight line?
kiruha [24]

Acceleration can be found using one of the following suvat equations:

v=u+at\\s=ut+\frac{1}{2}at^2\\s=vt-\frac{1}{2}at^2\\v^2-u^2=2as

Explanation:

The acceleration of an object is defined as the rate of change of velocity of the object:

a=\frac{v-u}{t}

where

v is the final velocity

u is the initial velocity

t is the time taken for the velocity to change from u to t

There are several equations used to find the acceleration of an object moving in a straight line (they are usually called suvat equation). Depending on which quantities are given in the problem, you can use one of the following equations:

v=u+at\\s=ut+\frac{1}{2}at^2\\s=vt-\frac{1}{2}at^2\\v^2-u^2=2as

where

a is the acceleration

s is the distance covered

t is the time

u is the initial velocity

v is the final velocity

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

<u>Momentum(p) of the bullet:</u>

p = mv

p = 0.05 * 1000

p = 50 kg m/s

<u>Finding the recoil force:</u>

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

<u>Finding the number of bullets fired in a minute:</u>

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

If a motorcyclist accelerates from rest to 40 m/s in 8 seconds, what is their acceleration?
IgorC [24]

Answer:

5 m/s²

Explanation:

Given:

v₀ = 0 m/s

v = 40 m/s

t = 8 s

Find: a

a = (v − v₀) / t

a = (40 m/s − 0 m/s) / 8 s

a = 5 m/s²
