The position of the object can be used to find the kinetic energy in terms of k and a.

<h3>What is kinetic energy?</h3>

The term kinetic energy refers to the energy of an object that is in motion. The question is incomplete hence the syetem is not shown and the value of the kinetic energy can not be found in terms of k and a.

Hence, when the system is shown, we can look at the position of the system and use it to obtain the value of the kinetic energy in terms of k and a.

Which quantities are vectors

Zarrin [17]

Answer:

For example, displacement, velocity, and acceleration are vector quantities, while speed (the magnitude of velocity), time, and mass are scalars. To qualify as a vector, a quantity having magnitude and direction must also obey certain rules of combination.

1. A 20m steel wire is stretched to 20.0m by

Eduardwww [97]

Answer:

Force to stretch the wire is 250 N

Explanation:

As we know that modulus of elasticity will remain the same for the wire if the applied stretch to the wire is within elastic limit

So we will have

$\frac{F L}{\Delta L A} = constant$

now we have

$\frac{F_1 L}{\Delta L_1 A} = \frac{F_2 L}{\Delta L_2 A}$

so we can write it as

$F_2 = \frac{F_1 L_2}{L_1}$

$F_2 = \frac{50 (0.05)}{0.01}$

$F_2 = 250 N$

Unit of work is derived unit why

adoni [48]

The unit for work J can also be written as Nm. Therefore, it is a derived unit as different SI units are needed to obtain its value. In this case, its derived from force and distance.
