2. V = D/T 75 km/1.5 hr = 50 km/hr D = V x T 30 km/hr x 2 hrs = 60 km
T = D/V
1075 miles/50 mph = 21.5 hours
D = V x T
30 km/hr x 2 hrs = 60 km

3. 90 km/hr – 50km/hr = 40 km/hr
40 km/hr/5 sec = 8 km/hr/s
Force = Mass X Acceleration
300 kg x 4m/s2 = 1200 Newtons
Weight = Mass x Acceleration of Gravity
60 kg x ~10 m/s2 = 600 Newtons
Work = Force X Distance
50 N x 80 m = 4000 joules

4. Distance = Work/Force
250 joules/200 N = 1.25 meters
Force = Work/Distance
20 joules/2 meters = 10 Newtons
Effort distance/resistance distance
8 m/2 m = MA of 4
Resistance force/effort force
600 N/200 N = MA of 3

5. Density = Mass/Volume
47.25 g/17.5 cm3 = 2.7 gm/cm3
Mass = Density x Volume
2.0 gm/cm3 X 5 cm3 = 10 g
Volume = Mass/Density
320 g/4 g/cm3 = 80 cm3

6. Q = mcΔT
20 g x J/gOC x 20 OC = Joules
455 J = 25 g X c X 130 OC
455J = 3250c (then divide both sides by 3250)
0.14 J/gOC
41840 J = ? g X J/gOC X 5 OC
41840 J = J/g (then divide both sides by 20.92)
2000 g

7. I = V/R
260 v/0.4 Ω = 650 amps
V = IR
15 amps X 225 Ω = 3375 volts
R = V/I
2400 v/250 amps = 9.6 Ω

11. Question 3 – DOK 3

12. Question 4 – DOK 2
To solve:
Divide 1,392 by 464 to find out how many half-lives have passed.
That equals 3.
After 3 half-lives, 12.5% of the material would remain
256 x 12.5 = 32
