Answer:
1 is the power of ten.
Explanation:
is deka.
Basically 10 is deka, same result as .
An object of mass m attached to a spring of force constant k oscillates with simple harmonic motion. The system's potential energy when kinetic energy of (3/4) E is (1/8) k A².
<h3>What is mechanical energy?</h3>
Mechanical energy is the sum of potential energy and kinetic energy.
Total mechanical energy = P.E max = K.E max
Total mechanical energy = K.E +P.E
Given is the kinetic energy is (3/4)E.
E= (3/4)E + P.E
P.E = (1/4) E
Maximum potential energy =E = (1/2) k A²
Here. A is the maximum displacement and k is the spring constant.
The potential energy at kinetic energy of (3/4) E is
P.E = (1/4)E = (1/8) k A²
Therefore, the system's potential energy when kinetic energy of (3/4) E is (1/8) k A².

Answer:
Below
Explanation:
The cars upward accel adds to the gravity accel (think about how suddenly heavy you feel when the elevator starts to move upward)
F = tension = ma
= 1400 * ( .7 + 9.81) = 14714 N
Answer:
Get out if the car
Explanation:
Get out of the car because the car could explode by over eclectic power
