Listena bullet traveling at 5.0 × 102 meters per second is brought to rest by an impulse of 50. newton-seconds. what is the mass of the bullet? 2.5 × 104 kg1.0 × 101 kg1.0 × 10-1 kg1.0 × 10-2 kg

The mass of the bullet = 1.0 × 10⁻² kg

Explanation:

Impulse: The impulse of a body is defined as the product of force and time, or it can also be defined as the product of mass and change in velocity of that body. The S.I unit of impulse is newton - second or kg m/s

impulse = I = M(u-v)

Making M the subject of the equation above,

M = I/(u-v) Equation 1

Where I = impulse of the bullet, M = mass of the bullet, V = final velocity of the bullet, u = initial velocity of the bullet.

Given: I = 5.0 Newton - second, v = 0 (brought to rest), u = 5.0 ×10² m/s

Substituting these values into equation 1

M = 5/ (5.0 ×10²)

M = 1.0 × 10⁻² kg.

The mass of the bullet = 1.0 × 10⁻² kg

attach the statements so i can answer : )

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
