Answer 1

Draw FBD

Answer 2

@Yahoo! solve this...it is for you...i will assume your kinematics is prepared

Answer 3

u sure the information is enough

Answer 4

decelleration = 0.5m/s^2

Answer 5

@zaphod Do u have answer key

Answer 6

Now, find alpha

Answer 7

i knw how to do the next one...i think we have to resolve it
a = -g ( sin alpha)

Answer 8

mg sin x = ma

Answer 9

sin x = a/g

Answer 10

x = sin^-1 a/g

Answer 11

@ajprincess wat do u think?

Answer 12

@eigenschmeigen

Answer 13

for a) assuming constant acceleration, v^2 = u^2 + 2as

Answer 14

Yes.....we want 2 nd question

Answer 15

6.25 = 2.25 + 8a

a = 1/2

Answer 16

now \[mgsin \alpha = ma\]
