<u>Answer:</u> This force will cause the motion in an object.

<u>Explanation:</u>

Unbalanced force is defined as the forces which are not equal in magnitude. When two forces with different magnitudes are applied on an object from opposite directions, the object will start moving in the direction of the net force.

These forces result in the motion of an object.

Balanced forces are the forces which are equal in magnitude. When two forces with equal magnitude are applied on an object from opposite directions, the object will not start moving.

These forces does not result in the motion of an object.

Hence, this force will cause the motion in an object.

A train started from rest and moved with constant acceleration. At one time it was traveling 27 m/s, and 150 m farther on it was

AlekseyPX

Explanation:

(a) Given:

Δx = 150 m

v₀ = 27 m/s

v = 54 m/s

Find: a

v² = v₀² + 2aΔx

(54 m/s)² = (27 m/s)² + 2a (150 m)

a = 7.29 m/s²

(b) Given:

Δx = 150 m

v₀ = 0 m/s

a = 7.29 m/s²

Find: t

Δx = v₀ t + ½ at²

150 m = (0 m/s) t + ½ (7.29 m/s²) t²

t = 6.42 s

v₀ = 0 m/s

v = 27 m/s

a = 7.29 m/s²

Find: t

v = at + v₀

27 m/s = (7.29 m/s²) t + 0 m/s

t = 3.70 s

(d) Given:

v₀ = 0 m/s

v = 27 m/s

a = 7.29 m/s²

Find: Δx

v² = v₀² + 2aΔx

(27 m/s)² = (0 m/s)² + 2 (7.29 m/s²) Δx

Δx = 50 m

A 1500-kilogram car is at rest on a level track. The driver gives the engine gas and the car begins to accelerate forward. The c

Nutka1998 [239]

1. The acceleration of the car is 3.375 m/s².

2. The force moving the car is 5062.5 N

From the question given above, the following data were obtained:

Mass of car = 1500 Kg

Initial velocity (u) = 0 m/s

Final velocity (v) = 27 m/s

Time (t) = 8 s

<h3>Acceleration (a) =? </h3><h3>Force (F) =? </h3>

<h3>1. Determination of the acceleration </h3>

Initial velocity (u) = 0 m/s

Final velocity (v) = 27 m/s

Time (t) = 8 s

<h3>Acceleration (a) =?</h3>

$a = \frac{v - u}{t} \\\\a = \frac{27 - 0}{8} \\\\a = \frac{27}{8}\\$

Therefore, the acceleration of the car is 3.375 m/s²

<h3>2. Determination of the force moving the car.</h3>

Mass of car = 1500 Kg

Acceleration (a) = 3.375 m/s²

<h3>Force (F) =?</h3>

F = 1500 × 3.375

Therefore, the force moving the car is 5062.5 N

A dish with a mass of 0.4 kg has a force of kinetic friction of 0.15 N exerted on it by moving a tablecloth for a time of 0.2 s.

Hatshy [7]

Answer:

the dish's acceleration is 0.375 m/s^2.

Explanation:

Recall the formula from Newton's 2nd Law:

Force = mass x acceleration.

Since we know the force in the direction of the movement (0.15 N), and we know the mass of the object (0.4 kg) , its acceleration is given by:

acceleration = force / mass = 0.15 N / 0.4 kg = 0.375 m/s^2
