find initial velocity with the given: time=1.37s, gravity accelaration=-9.8m/s^2,distance=-1.0m

Question

its about projectiles but im using one of the kinematics formula d=vi(t)+(1/2)(a)(t)^2 to find initial velocity but im having hard time with it.

Answer 1

d = distance

v_i = initial velocity

a = gravity acceleration

t = time

 

 

Given:

d = -1 m

a = 9.81 m/s²

t = 1.37 s

 

Unknown:

v_i

 

Just plug in these values into the formula you have to solve for v_i.
