The spring, initially at rest, was compressed by the blue box by 0.15 m. The spring constant of the spring is 300 N/m. The mass

of the box was 0.2 kg. What is the max height of the box when it comes to rest on the ramp

Answer:

1.72m

Explanation:

Step 1:

Data obtained from the question.

Displacement (x) = 0.15 m

Spring constant (K) = 300 N/m

Mass (m) = 0.2 kg

Height (h) =?

Step 2:

Determination of the energy in the spring.

The energy is a spring can be obtained by the following equation:

E = 1/2 kx^2

E = 1/2 x 300 x 0.15^2

E = 150 x 0.0225

E = 3.375J

Step 3:

Determination of the maximum height.

At maximum height, the energy stored is the spring is equal to the potential energy i.e

Energy stored in the string = potential energy

E = P.E

Recall:

Potential energy = mgh

Where:

m is the mass = 0.2kg

g is the acceleration due to gravity = 9.8m/s2

h is the height. =?

Potential energy (P.E) = 3.375J

PE = mgh

3.375 = 0.2 x 9.8 x h

Divide both side by 0.2 x 9.8

h = 3.375/ (0.2 x 9.8)

h = 1.72m

Therefore, the maximum height of the box is 1.72m

NikAS [45]

Answer:

The gazelles top speed is 27.3 m/s.

Explanation:

Given that,

Acceleration = 4.2 m/s²

Time = 6.5 s

Suppose we need to find the gazelles top speed

The speed is equal to the product of acceleration and time.

We need to calculate the gazelles top speed

Using formula of speed

v=at

Where, v = speed

a = acceleration

t = time

Put the value into the formula

v=4.2\times6.5

v=27.3\ m/s

Hence, The gazelles top speed is 27.3 m/s.

Two balls are thrown against a wall. Ball 1 has a much higher speed than ball 2.
Sunny_sXe [5.5K]

Let both the balls have the same mass equals to m.

Let v_1 and v_2 be the speed of the ball1 and the ball2 respectively, such that

v_1>v_2\;\cdots(i)

Assuming that both the balls are at the same level with respect to the ground, so let h be the height from the ground.

The total energy of ball1= Kinetic energy of ball1 + Potential energy of ball1. The Kinetic energy of any object moving with speed, v, is \frac 12 m v^2

and the potential energy is due to the change in height is mgh [where g is the acceleration due to gravity]

So, the total energy of ball1,

=\frac 12 m v_1^2 + mgh\;\cdots(ii)

and the total energy of ball1,

=\frac 12 m v_2^2 + mgh\;\cdots(iii).

Here, the potential energy for both the balls are the same, but the kinetic energy of the ball1 is higher the ball2 as the ball1 have the higher speed, refer equation (i)

So, \frac 12 m v_1^2 >\frac 12 m v_2^2

Now, from equations (ii) and (iii)

The total energy of ball1 hi higher than the total energy of ball2.
