u=initial velocity
v=final velocity
a=acceleration
s=distance travelled
t=time taken to travel the distance
u= 10 m/s
v= 0 m/s
t= 20 secs
a= v-u/t= -10/20= -0.5 m/s^2
s= -u^2/2*a
s= 100/1= 100 m
v=final velocity
a=acceleration
s=distance travelled
t=time taken to travel the distance
u= 10 m/s
v= 0 m/s
t= 20 secs
a= v-u/t= -10/20= -0.5 m/s^2
s= -u^2/2*a
s= 100/1= 100 m
s=100......
what does s and all alphabets mean
edited it in the answer
smeans displacement
nope
m not asking m telling
