A 0.005 kg bullet is travelling horizontally at a velocity of 250 m/s when it strikes a wooden block of mass 12 kg on a table at
Verdich [7]
Use the conservation of momentum formula: m1v1 + m2v2 = v(m1 + m2)

(0.005kg)(250m/s) + (12kg)(0m/s) = v(0.005kg + 12kg)

v = ((0.005kg)(250m/s)) / (0.005kg + 12kg)

v = 0.104 m/s

Action and reaction forces are described by which of Newton’s laws of motion?
nikdorinn [45]

Answer:

third

Explanation:

for every action there is an equal and opposite reaction

example

bouncing ball

ball receives a force from the ground due to collision

that same force causes the ball to bounce off the ground

first law:

inertia

example

stuff in space doesn't move unless its pushed

then it keeps going unless something stops it

second law

force = mass times acceleration

example

harder you push a cart the faster it goes

the less a cart weighs the faster a cart goes

The gravitational acceleration on Earth is 9. 8 m/s2. What is the weight of a car on Earth (to the nearest whole number) if it h
astraxan [27]

Hi there!

Recall the equation for weight.

W = Mg

W = Weight (N)

M = Mass (kg)
g = acceleration due to gravity (m/s²)


The weight of an object depends upon its MASS and the strength of the GRAVITATIONAL field. We can solve for weight:

W = 1360 * 9.8 = \boxed{13,328 N}
