Answer:b

Explanation:

velocity of a falling object increases.

so Kinetic energy of a falling object increases

height of a falling object from the ground decreases.

so the potential energy of a falling object decreases

Illusion [34]

Objects in free fall, disregarding terminal velocity, accelerate at 9.8(m/s)/s. so for every second it was falling, it gained 9.8m/s in speed. 9.8 * 10 = 98m/s

A block slides down a slope inclined at 37 degrees. If the slope is frictionless and the block starts off at rest, how fast is i

Answer:

Vf= 3.435 m/s

Explanation:

Given:

Initial velocity Vi =0 m/s (starting from Rest position)

θ = 37⁰

Distance S = 1 m

To find: Final Velocity Vf=?

fist we have to find the down slope net acceleration a = g sin θ

a= 9.81 sin 37⁰ = 5.9 m/s²

By 3rd equation of motion

2 a S= Vf² - Vi²

Vf = Square root ( 2 × 5.9 m/s² × 1 + 0 m/s)

Vf = Square root (11.8)

Vf= 3.435 m/s

What is the relationship between the acceleration of an object change in relation to its mass

yarga [219]

The relationship between mass and acceleration is an inverse proportionality

Explanation:

The relationship between the acceleration of an object and its mass is given by Newton's second law, which states that:

$F=ma$

where

F is the net force on the object

m is its mass

a is its acceleration

From the equation, we notice that if the force on the object is kept constant, then the mass and the acceleration are inversely proportional to each other. This means that:

If the mass of the object is increased, its acceleration will decrease
If the mass of the object is decreased, its acceleration will increase
