Question

what is the acceleration of a 1000 newton box on a 30 degrees frictionless ramp?

Answer 1

i think u know the equation\[F=mg\]

Answer 2

\[or, 1000=m \times10\]

Answer 3

or, m=100 kg

Answer 4

now we know that\[F=ma\]

Answer 5

here F will b thw force along the plane of ramp
m= mass of the body
a=acceleration

Answer 6

so\[1000 \times \cos 60=100a\]

Answer 7

if u need any more explanation plz ask me

Answer 8

just solve this equation for acceleration a

Answer 9

this f=mg doesn't work here because its inclined plane

Answer 10

funnily, though, since there is no friction, there is no need to take note of how heavy it is.
a simply is a component of g

so, \(a=g sin 30\)
or, \(a=10*0.5=5ms^{-2}\)
