6 0

Answer:

4116J

Explanation:

Given parameters:

Mass of the person = 70kg

Height of the ladder = 6m

Unknown:

Work done = ?

Solution:

The work done by the person climbing is the same as the potential energy.

Work done is the force applied to move a body through a distance;

So;

Potential energy = mass x acceleration due to gravity x height

Therefore;

Potential energy = 70 x 9.8 x 6 = 4116J

A 0.20-kg mass is oscillating on a spring over a horizontal frictionless surface. When it is at a displacement of 2.6 cm for equ

valentinak56 [21]

Explanation:

The given data is as follows.

mass = 0.20 kg

displacement = 2.6 cm

Kinetic energy = 1.4 J

Spring potential energy = 2.2 J

Now, we will calculate the total energy present present as follows.

Total energy = Kinetic energy + spring potential energy

= 1.4 J + 2.2 J

= 3.6 Joules

As maximum kinetic energy of the object will be equal to the total energy.

So, K.E = Total energy

= 3.6 J

Also, we know that

K.E = $\frac{1}{2}mv^{2}_{m}$

or, v = $\sqrt{\frac{2K.E}{m}}$

= $\sqrt{2 \times 3.6 J}{0.2 kg}$

= $\sqrt{36}$

= 6 m/s

thus, we can conclude that maximum speed of the mass during its oscillation is 6 m/s.
