Question 4
A
Vibratory and translational motion
B
Random and translational motion
C
Rotational mand oscillatory motion
D
Translational and rotational motion
##### Explanation

The tyre in motion makes a rotation and it translates in a straight line alongside. if the wheels is turned it continued further in a translational straight line through rotational motion.

Question 5
A
12ms-1
B
144ms-1
C
72ms-1
D
36ms-1
##### Explanation
V2 = U2 x 2ax
V2 = 0 x 2(3)(24)
V2 = 144
V = $$\sqrt{144}$$
V = 12ms-1

Question 6
A
25.3kms-1
B
4.2kms-1
C
4.0kms-1
D
11.3kms-1
##### Explanation
Vescape = $$\sqrt{2gR}$$
Vescape = $$\sqrt{2\times10\times6.4\times10^6}$$
Vescape = $$\sqrt{128000000}$$
Vescape = 11313.7085mS-1
Vescape = 11.313kmS-1
