Question

A toy rocket has a mass of 350g at launch.the force it produces is 15N and it is fired at angle of 65⁰ to the horizontal.what is the initial acceleration of the rocket as a vector?

Answer 1

F = 15(cos65⁰ i + sin65⁰ j)
F = ma, so a = F/m

Answer 2

but what about g ?
F = 15 cos 65 i + (15 sin 65 - mg) j

Answer 3

In my view
F=(15cos 65, 15sin65- mg)
then acceleration
a=F/m =15cos65/0.35kg, 15sin64-0.35*9.8/0.35)

Answer 4

18.6,32
