#### Slide 7 -Quizvraag

10 m/s = ... km/h
A
3,6
B
36
C
10 000
D
2,8

#### Slide 8 -Quizvraag

A
1000 m
B
1150 m
C
1320 m
D
1530 m

#### Slide 9 -Quizvraag

Calculate the average speed
A
10 m/s
B
15 m/s
C
18 m/s
D
20 m/s

#### Slide 10 -Quizvraag

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 -Quizvraag

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

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 -Quizvraag

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

C
0.009 kg
D
51.4

Given:

Solution:

Fres<0
Fres>0
Fres=0
