Answer:
k = 773.64 N/m
Explanation:
Given:
mass of the pellet, m = 3.56 x 10² kg
Compression in spring, x = 6.61 × 10⁻² m
Height of rise of the pellet, h = 4.83 m
Now, let k be the spring constant
From the concept of conservation of energy, we get
gravitation potential energy acquired by the pellet will be from the energy provided by the spring
thus,
where, g is the acceleration due to the gravity
on substituting the values, we get
or
1.685 = .002178 × k
k = 773.64 N/m
Explanation:
Let the 2 be X and Y.
Z is 3rd angle.
Z=2X
w.k.t Sum of angles in a triangle is 180°
Z+X+Y=180°
2X+90°=180°
2X=90°
=>X=45°
=>Y=90°-45°=45°
=>Z=2X=2(45°)=90°
Hope this helps you.
Kinetic energy = 1/2 * mass in kg * speed squared
Answer:
Explanation:
For this exercise let's use hooke's law
F = - k x
where x is the displacement from the equilibrium position.
x = 
if we have several springs in series, the total displacement is the sum of the displacement for each spring, F the external force applied to the springs
x_ {total} = ∑ x_i
we substitute
x_ {total} = ∑ -F / ki
F / k_ {eq} = -F 
1 / k_ {eq} = ∑ 1 / k_i
if all the springs are the same
k_i = k
