Answer:
The average acceleration is 16.6 m/s² ⇒ 1st answer
Explanation:
A rocket achieves a lift-off velocity of 500.0 m/s from rest in
30.0 seconds
The given is:
→ The initial velocity = 0
→ The final velocity = 500 meters per seconds
→ The time is 30 seconds
Acceleration is the rate of change of velocity of the rocket
→ 
where a is the acceleration, v is the final velocity, u is the initial velocity
and t is the time
→ u = 0 , v = 500 m/s , t = 30 s
Substitute these values in the rule
→
m/s²
<em>The average acceleration is 16.6 m/s²</em>
Answer:
735 J
Explanation:
From the question given above, the following data were obtained:
Weight (W) = 49 N
Height (h) = 15 m
Potential energy =?
Potential energy is simply defined as the product of weight of the object and height to which the object is raised. Mathematically, it is expressed as:
Potential energy = weight × height
With the above formula, we can obtain the potential energy of the coconut as follow:
Weight (W) = 49 N
Height (h) = 15 m
Potential energy =?
Potential energy = weight × height
Potential energy = 49 × 15
Potential energy = 735 J
Thus, the potential energy of the coconut is 735 J
Answer:
x₂=0.44m
Explanation:
First, we calculate the length the spring is stretch when the first block is hung from it:

Now, since the stretched spring is in equilibrium, we have that the spring restoring force must be equal to the weight of the block:

Solving for the spring constant k, we get:

Next, we use the same relationship, but for the second block, to find the value of the stretched length:

Finally, we sum this to the unstretched length to obtain the length of the spring:

In words, the length of the spring when the second block is hung from it, is 0.44m.
