20m/s
can u click the picture of the question...if u dont mind
yah sure
is that ok
check i have sent u
yah i got it i had almost forgot to take acceleration negative
for these case
thank you
ya ....correct....good luck....
no its ok.....

initial velocity = u = 40 m/s
Acceleration = a = - 10 m/s*s ( as it is thrown upward)
time = t = 2 s
Using equation :
v = u + at
v = 40 - 10(2)
v = 20 m/s
Acceleration = a = - 10 m/s*s ( as it is thrown upward)
time = t = 2 s
Using equation :
v = u + at
v = 40 - 10(2)
v = 20 m/s
sorry your answer is not correct
the right answer is 20m/s
how?
Don't know i am also figuring out .how ?
I figured it out
yah right i almost forgot about this that it is thrown upwards
