If a car changes ita velocity from 32km/hr to 54km/hr in 8.0 seconds, what is its acceleration
Andrews [41]
Firstly, let's convert the velocities in km/hr to m/s
32*1000/3600=8.89m/s
54*1000/3600=15m/s
From the formula, acceleration=V-U/t
15-8.89/8=0.76m/s²
hope this helps.

A vector A⃗ has a length of 8.6 m and points in the negative x direction. Find the x component of the vector −3.7A⃗ .
77julia77 [94]

Answer:

31.8 m in the positive x-direction

Explanation:

Here we have an example of multiplication of a vector by a scalar.

In order to perform this operation, we have to:

- multiply the magnitude of the vector by the scalar

- reverse the direction of the vector if the scalar is a negative number

In this problem, the original vector has a lenght of 8.6 m and it points in the negative x direction. Now we have to find the vector -3.7A, so we have:

- The magnitude is obtained by calculating the product

(3.7)\cdot (8.6)=31.8 m

- The direction is reversed, because the scalar is -3.7, so the new vector will point in the positive x-direction

So the final vector is 31.8 m in the positive x-direction, and therefore its x-component is also 31.8 m in the positive direction.

What is the state of an object accelerating due to the force of gravity alone?
Marysya12 [62]

Answer:

Its state is in uniformly accelerated motion

Explanation:

When an object is acted upon the force of gravity only, we said that the object is in free fall.

According to Newton's second law of motion:

F=ma

where F is the net force on an object, m is its mass, a its acceleration, when the net force on an object (F) is non-zero, than the object accelerates (because a is non-zero), so the object is in accelerated motion.

In case of free fall, the rate of acceleration of the object is equal to g=9.8 m/s^2, the acceleration due to gravity, and it is constant. So, the object is moving by uniformly accelerated motion.

The initial speed of a body is 3.28 m/s. What is its speed after 2.32 s if it accelerates
Helga [31]
Final velocity = initial velocity + acceleration * time

v = u + at

v = 3.28 + 2.32 * 2.08

v = 3.28 + 4.83

<u>v = 8.11 m/s</u>
