C, due to stuff and whatnot
Answer:
25 m/s
Explanation:
First we should define the variables
T=4
Dx = 100
ay=-9.8
ax=0
We can use formula 1 from the BIG 5
x=(v+v0)t/2
By plugging in our variables we can get 100=4(v+v0)/2
Which is 50=v+v0
v=v0 since horizontal acceleration always equals zero
so 2v0 = 50
v0 = 25
The answer i think would be D
Answer:
it makes our work easy and
time saving
it multiply our force applied
it complete our work with high efficiency
by using this,less effort is required for the work.
