What type of reaction is being shown in this energy diagram?
energy
activation
energy
reacions
o
a. exothermic, because the products are higher in energy
o
b. endothermic, because the reactants are higher in energy
c. endothermic, because the products are higher in energy
d. exothermie, because the reactants are higher in energy

Did you ever figue this

Idon't know it i just need my points lol

Initial velocity,  u = 4.9 m/sfinal velocity = v m/sinitial height,  h₁ =  245 m    final height, h₂ = 0a = -9.8  m/s²time taken = t secondss = ut + 0.5at²⇒  (h₂-h₁) = ut + 0.5at²⇒  0-245 = 4.9t + 0.5×(-9.8)×t²⇒ -245 = 4.9t - 4.9t²⇒ 4.9t² -4.9t -245 =0solving it, we get   t = 7.59sv  = u +  at = 4.9 -9.8×7.59 = 4.9 - 74.38 = -69.48 m/svelocity is  69.48 m/s downward
