Karen has a mass of 57.9 kg as she rides the up escalator at Woodley Park Station of the Washington D.C. Metro. Karen rode a dis
liq [111]

Answer:22537.92 J

Explanation:

Given

mass of karen \left ( m\right )=57.9 kg

Distance covered by Karen =69.6 m

acceleration due to gravity=9.8

inclination=34.8^{\circ}

vertically karen move

h=69.6\times \sin \left ( 34.8\right )

h=39.72 m

Work done by escalator on karen is equal to change in potential energy of  karen

\Delta P.E.=m\times g\times \Delta h

\Delta P.E.=57.9\times 9.8\times 39.72=22537.92 J

A 1,500 kg car hits a boulder with a force of 500 N, and the collision takes 0.5
Anuta_ua [19.1K]

Answer: C.

250 kg-m/s

Explanation:

Given that the

Mass M = 1,500 kg

Force F = 500 N

Time t = 0.5 seconds

From Newton's second law of motion which state that the rate of change of momentum is proportional to the applied force.

F = mV/t

Ft = mV

Where ft = impulse: the product of time and applied force

Substitutes force and time into the formula

Ft = 500 × 0.5 = 250 Ns
