Near the Earth's surface, a freely falling body has constant acceleration at every instant of its fall ... 9.8 meters per second^2.

Can you change your mass without changing your weight?

Ratling [72]

No, because mass is the amount of matter in something and weight is the pull of gravity on a object, for example you would weigh 65 pounds.. and have the mass of 1058..if you were in space your weight would change but your mass will always stay the same

Answer:

$m_l=550\ kg$ is the mass of librarian.

Explanation:

Given:

mass of the system, $m_s=3.3\times 10^{3}\ kg$

velocity of librarian relative to the ground, $v_l=2.5\ m.s^{-1}$

velocity of the cart relative to the ground, $v_c=0.5\ m.s^{-1}$

N<u>ow using the principle of elastic collision:</u>

Net momentum of the system is zero.

$m_l\times v_l=(3300-m_l)\times v_c$

$m_l\times 2.5=(3300-m_l)\times 0.5$

$m_l=550\ kg$ is the mass of librarian.

Explain how the gravitational potential energy of an object can be changed.

inna [77]

Answer:

Change in Potential energy, pe = Final potential energy - Initial potential energy

Explanation:

∆p.e = Final p.e - Initial p.e

From the equation ∆p.e = (mgh) final - (mgh) initial
