A
10 m/s
B
15 m/s
C
18 m/s
D
20 m/s

Slide 10 - Quiz

Calculate the acceleration
A
0.17 m/s^2
B
6 m/s^2
C
0.33 m/s^2
D
3 m/s^2

Slide 11 - Quiz


In which of the two cases is the distance covered the greatest?
A
Left
B
Right

Slide 12 - Quiz


A
1.7 m/s^2
B
2.2 m/s^2
C
1.3 m/s^2
D
0.6 m/s^2

Slide 13 - Quiz

Calculate the acceleration
500 N
350 N
670 kg
friction = 450 N
Fres = 500 + 350 - 450 = 400 N
Fres = m x a
400 = 670 x a 
a = 400/670 = 0.6 m/s2

Slide 14 - Slide
