We will apply the Newton's second Law so the we will be able to find the acceleration.
F (tot) = ma
a = F(tot) /  m
a = 32.0 N / 65.0 kg = 0.492 m/s^2
Approximately 0.492 m/s^2 is her initial acceleration if she is initially stationary and wearing steel-bladed skates.

nadya68 [22]

Answer:

KE=1.3\times 10^{21}\ J

KE=3.1\times 10^{5}\ E

Explanation:

(a)

Given:

  • mass of comet, m=4.2\times 10^{12}\ kg
  • velocity of the comet, v=2.5\times 10^4\ m.s^{-1}

<u>Now, the kinetic energy of the comet can be given by:</u>

KE=\frac{1}{2} m.v^2

KE=0.5\times 4.2\times 10^{12}\times (2.5\times 10^4)^2

KE=1.3\times 10^{21}\ J

(b)

Given:

  • energy released by 1 megaton of TNT, E=4.2\times 10^{15}\ J

<u>Now the kinetic energy of the comet in terms of energy of 1 megaton TNT:</u>

KE=\frac{1.3\times 10^{21}}{4.2\times 10^{15}} E

i.e.

KE=3.1\times 10^{5}\ E

A typical meteor that hits the earth's upper atmosphere has a mass of only 2.5 g, about the same as a penny, but it is moving at
attashe74 [19]

Answer:

Answer:u=66.67 m/s

Explanation:

Given

mass of meteor m=2.5 gm\approx 2.5\times 10^{-3} kg

velocity of meteor v=40km/s \approx 40000 m/s

Kinetic Energy of Meteor

K.E.=\frac{mv^2}{2}

K.E.=\frac{2.5\times 10^{-3}\times (4000)^2}{2}

K.E.=2\times 10^6 J

Kinetic Energy of Car

=\frac{1}{2}\times Mu^2

=\frac{1}{2}\times 900\times u^2

\frac{1}{2}\times 900\times u^2=2\times 10^6  

900\times u^2=4\times 10^6

u^2=\frac{4}{9}\times 10^4

u=\frac{2}{3}\times 10^2

u=66.67 m/s

5. A cart with one fan on It blowing to the left and carrying one block produces the x vs t graph shown If this car were carryin
kumpel [21]

Answer:

Graph C

Explanation:

With the same force and more mass, the position in time will still be parabolic

i.e.  x = ½at², but the rate of acceleration will be lower so the position curve will be broader.
