Answer on Mechanics | Relativity Question for Jessica
98/9,8 = 10 kg.
Using the Newton's Second Law
F = ma. So, the cart's
acceleration is a = F/m = 40/10 = 4 m/s^2.
As the initial speed was zero, we
get the equation for displacement and final speed:
S = a*t^2/2, V = at.
V = a*sqrt(2*S/a) = sqrt(2*S*a) = sqrt(2*12*4) = sqrt(96) =
