A car drives at an average speed of 54km/h for 1 hour and 20 minutes. What was the distance covered by the car in km?​
VLD [36.1K]

Answer:

\huge\boxed{\sf S = 71.82\ km}

Step-by-step explanation:

<u>Given:</u>

Speed = v = 54 km/h

Time = 1 hour 20 min = 1 hour (20/60) hour = 1.33 hrs

<u>Required:</u>

Distance = S = ?

<u>Formula:</u>

S = vt

<u>Solution:</u>

S = (54)(1.33)

S = 71.82 km

\rule[225]{225}{2}

Ignoring friction and air resistance, what is the acceleration of the box, to the nearest tenth? 0.5 m/s2 4.9 m/s2 8.5 m/s2 9.8
rosijanka [135]

The option second -4.9 m/s² is correct the negative sign shows that a positive direction "upward along the ramp".

<h3>What is mass?</h3>

A tangible body's mass is the amount of matter it possesses. It's also a metric of inertial, or the resistance to velocity when a net force is exerted.

The question is incomplete.

The complete question is:

A box that has a mass of 80 kg slides down a ramp with a 30-degree angle. The free-body diagram shows the forces acting on the box. Ignoring friction and air resistance, what is the acceleration of the box, to the nearest tenth?

-0.5 m/s²

-4.9 m/s²

-8.5 m/s²

-9.8 m/s²

First we calculate the weight:

W = mg = 80×9.8

W = 784 N

The weight component parallel to the ramp is:

W₁ = Wsin30

W₁ = (784)(sin30)

W₁ = 392 N

From the Newton's second law:

a = F/m

a = 392/80

a = 4.9 m/s²

Thus, the option second -4.9 m/s² is correct the negative sign shows that a positive direction "upward along the ramp".

Identify the graph of the equation. What is the angle of rotation for the equation?
borishaifa [10]

Answer:

d. parabola, 0°

Step-by-step explanation:

y² + 8x - 0

y² = -8x

Where x = cos t  ,  y = sin t

Sin² t = -8 Cos t

1 - Cos² t = -8 Cos t

- Cos² t + 8 Cos t + 1 = 0

t = 2лπ ± (3 + √10) , л∈Z
