question 3 last part is graph

Answer 2

question 6 has two parts about drawing on the graph
so please take a look at them @Mashy

Answer 3

Did you find the time of constant acceleration and deceleration?

Answer 4

@somy?

Answer 5

yes

Answer 6

weight = m × g
= 130.5 × 9.81 = 1280 N

Answer 7

tension b i) F = ma
T – 1280 = 130.5 × 0.57
T = 1280 + 74.4 = 1350 N

Answer 8

tension b ii) 1280 N
coz constant velocity means no acceleration so only gravity acts on the body thats why its weight

Answer 9

Deceleration
1240 – 1280 = 130.5 × a
a = (–) 0.31ms-2

Answer 10

d i) 3.5 s
d ii) 6.5 s

Answer 11

ok this is the whole info
so please now how do i draw the graph?

Answer 12

great!
now draw a table of the time and the corresponding velocities.

Answer 13

first twenty seconds a straight line?

first 3.5 seconds, its accelerating with 0.57 m/s^2 .. so velocity is increasing gradually from 0 to 2m/s from t = 0 to t = 3.5 seconds.

can u draw this first part?

Answer 14

oughhh ok lets see @Mashy

Answer 15

plot the points!

Answer 16

@random231
has done it all ..

Random.. u pass the Cambridge course.. congrats xD

Answer 17

owwwwwwwwww im so stupid
thank u!!!!!!!!!!!!!!!!!!!!!! @random231

Answer 18

@random231

last deceleration is for 6.5 seconds ya?!

(thats what somy calculated :P.. i didn't calculate)

if that is so, then 23.5 + 6.5 = 30s ya?!

Answer 19

OOH Sorry didnt notice the .5 yeah mashy you are right and @Somy pls correct it!!
