Question 1

Hastighet

Answer 1

ds/dt

Question 2

ds/dt

Answer 2

Hastighet

Question 3

Acceleration

Answer 3

dv/dt eller d^2s/dt^2

Question 4

d^2s/dt^2

Answer 4

Acceleration

Question 5

skriv om dv/dt m.a.p. sträckan

Answer 5

dv/dt=> dv/dt * ds/ds => dv/ds *ds/dt => dv/ds * V

Question 6

skriv om dv/ds * V m.a.p. tiden

Answer 6

dv/ds * V => dv/ds *ds/dt => dv/dt * ds/ds => dv/dt

Question 7

skriv om dv/dt till s(V)

Answer 7

dv/dt= dv/dt * ds/ds = dv/ds *ds/dt = dv/ds * V => a(V)=dv/ds * V =>int(vdv/a(V))v=int(ds)s=s-s0 => s=s(V)

Question 8

skriv om dv/dt till t(V)

Answer 8

dv/dt=a(V) => int(dv/a(V))v=int(dt)t=> t-t0 => t(V)

Question 9

dv/dt

Answer 9

acceletration

Question 10

kinetisk energi

Answer 10

mV^2/2

Question 11

skriv om F=G((m1m2)/s^2) m.h.a. NII till ett uttryck med g där m2=M_E

Answer 11

F=ma => ma=G((m1m2)/s^2) => a=Gm2/s^2 =>(f=mg)=> g=Gm2/s^2 =>(definierar jordens yta som utgångspunkt)=>g=g*Re^2/s^2 (vid jordens yta Re^2=s^2=> g=g

Question 12

kinetisk energi

Answer 12

1/2*mV^2

Question 13

1/2mV2^2-1/2mV1^2

Answer 13

arbete

Question 14

arbete

Answer 14

1/2mV2^2-1/2mV1^2

Question 15

Answer 15

ymgs (y=my)

Question 16

mV

Answer 16

rörelsemängd

Question 17

rörelsemängd

Answer 17

mV
