– Accelerate at 10m/s^2
The Train… of Pysics!
What trajectory would the apple follow?
In physics motion at constant speed is indistinguishable from being at rest!
10m = 0 + 1/2a(4.47)^2
N = Normal(perpendicular)
FN mg=weight, mg is equal to FN

if α=30°、Fr=100N sin(30degree)*100
FRX = 50N, Fry = 86.6N cos(30degree)*100
m = 10Kg
mg = 100N
Fry = 50N
Fn = 150N
Frx = 86.6N
Fw = 86.6N
