Hi there!

We know that:

Force due to gravity = Mgsinθ

Force due to friction = μMgcosθ

Let the positive direction be directed in the direction of the block's acceleration, which is downward.

Thus:

ΣF = Mgsinθ - μMgcosθ

Solving for acceleration requires diving all terms by the mass, so:

a = gsinθ - μgcosθ

Substitute in given values. (g = 9.8 m/s²)

a = 9.8sin(30) - 0.3(9.8)cos(30) = 2.354 m/s²

How does friction affect object acceleration down an incline?
Colt1911 [192]

Friction is the force that acts on the opposite side of direction of force, thus it manages to decelerate an object, so it acts upward along the plane

A rolling ball has 3,276) of energy, what is it's mass when it is rolling at a velocity of 53m/s? what is the mass​
hram777 [196]

Initial velocity U = 0

Final velocity V = 32.23 m/s

Explanation:

Given that a coin is dropped from the top of the Tower of Pisa, 53m above the ground.

What is the coin's initial velocity ?

Since the coin is dropped from the tower, the initial velocity U will be equal to zero.

Therefore, U = 0

But the final velocity V will be calculated by using the formula

V^2 = U^2 + 2gH

V^2 = 0 + 2 × 9.8 × 53

V^2 = 1038.8

V = sqrt ( 1038.8)

V = 32.23 m/s

sorry if did not help :(

To understand the distinction between mass and weight and to be able to calculate the weight of an object from its mass and Newt
Firdavs [7]

Answer: A.E.

Explanation: To understand the distinction between mass and weight and to be able to calculate the weight of an object from its mass and Newton's law of gravitation. The concepts of mass and weight are often confused. In fact, in everyday conversations, the word "weight" often replaces "mass," as in "My weight is seventy-five kilograms"

The graph in the accompanying figure (Figure 1) shows the magnitude of the force exerted by a given spring as a function of the
serious [3.7K]

The elastic potential energy stored in the stretched spring is 1 J.

<h3>What is Hooke's law?</h3>

Hooke's law states that; provided the elastic limit is not exceeded, the extension of the spring is directly proportional to the force on the spring.

Given that;

Force on the spring = 350 Newton

Distance stretched = 7 centimeters or 0.07 m

Hence;

F = ke

k = F/e = 350 Newton/0.07 m = 5000 N/m

Work done in stretching a spring = 1/2ke^2

= 0.5 × 5000 × (2 × 10^-2)^2 =1 J
