Question

The reaction time for an automobile driver is 0.7s.
If the automobile decelarated at 5m/s^2 calculate the total distance travelled by the automobile in coming to rest from an initial velocity of 8.33 m/s after a signal is observed.

Answer 1

bc isme kya problem h ?

Answer 2

bc kyu prob nahi h bas method verify karna tha

Answer 3

work dikha apna?

Answer 4

v^2 = u^2 + 2aS
0 = (8.33)^2 + 2aS
-69.38 = 10S
S = -6.938

magnitude taking we get S = 6.938m

now,
t = 0.7
s = 8.33

d = st = 0.7*8.33 = 5.831,

D = d+S=6.938+5.831 = 12.77=12.8m

Answer 5

a=-5
hoga na

Answer 6

deccelarate kr raha h

Answer 7

oops...baki sab sahi h na?

Answer 8

d=8.33 kaise ho gaya?

Answer 9

tera toh yeh aaya tha na
magnitude taking we get S = 6.938m

Answer 10

s*t karna
8.33*0.7 is 5.831

Answer 11

arrey! s=6.938 tha na

Answer 12

abe S = 6.938 tha m s VELOCITY chaman

Answer 13

theek se padhna bhai
tu muhje dara deta h

Answer 14

lol S se kyun donate krta h
v se krna

Answer 15

lol mujhe confuse kr diya

Answer 16

donate? do u mean DENOTE? XD

Answer 17

lol yea

Answer 18

ha tuh d = vt = 8.33*0.7 = 5.831
