The two balls have the same energy when they land, hence the ball with mass 4m is moving at a speed of v/2.

Speed is defined as the ratio of the distance traveled to the time required to cover that distance. Speed is a scalar since it just has a vector and no magnitude.

Normal speed: The ratio of an object's total distance traveled to the whole time it took it to cover that distance is its average speed. Instantaneous speed: An object's instantaneous speed is the speed it is moving at at any given time while it is moving at a variable speed.

Under constant acceleration,

the distance an object moves is given by d = 0.5 A T^2

d = 0.5 A (2T)^2 d = 0.5 A 4T^2 d

= 2AT^2 and 2AT^2/(0.5 AT^2)

The correct answer is 3.7 m

There are many forms of energy, which prevail, however, all these forms of energy generally come under two basic categories, that is, potential energy and kinetic energy. The different forms of potential energy are chemical energy, mechanical energy, gravitational energy, and nuclear energy.

Here, in this question,

Bullet with least kinetic energy will produce least compression.

And since the Kinetic energy of B is least so the compression produced will also be the least.

M(B) = 125 g

        = 8.099 * 10⁻³ kg

V(B) = 945 ft/s = 288.036 m/s

Now using the energy conservation,

(1/2)*M(B)*V(B) = 1/2*k*x²

8.099 * 10⁻³ * (288.036)² = 49 * x²

x² = 13.71

x = d = 3.7 m

Therefore the force constant at which the spring shows the least kinetic energy and compression is 3.7 m

Collisions between two objects are a fundamental part of the physical world. The collision process can be broken down into three distinct stages:  impact, compression and rebound.

Impact is when two objects come into contact and force is transferred from one object to the other. Compression follows impact and is the result of the objects being forced together, resulting in the objects being deformed. Rebound is the final stage and occurs when the deformation of the objects is released.

Resulting in the objects separating and returning to their original state. The impact stage of a collision is the most important as it’s what initiates the collision and determines how much force is transferred between the two objects. The compression stage of a collision is the result of the objects being forced together and deformed.

Torque on system = (mg) x r - (m xa)x r -

a = rα(net) (the relationship between linear and rotational acceleration)

Our bodies sense an upward push in the water that is equivalent to the weight of the water that is displaced.
