h = ut + 1/2 gt² find a by differentiating h twice w.r.t. a = g as F = ma so F = mg (answer)
F = 36 dyne at an angle of 60° Fₓ = F cos 60° = 18 dyne Fₓ = maₓ So aₓ = Fₓ/m = 1 cm/s²
Due to inertia of motion.
The motion of a particle of mass m is described by h = ut + 1/2 gt² . Find the force acting on particle. (F = mg)
h = ut + 1/2 gt² find a by differentiating h twice w.r.t. a = g as F = ma so F = mg (answer)
h = ut + 1/2 gt²
See lessfind a by differentiating h twice w.r.t.
a = g
as F = ma so F = mg (answer)
A force of 36 dynes is inclined to the horizontal at an angle of 60°. Find the acceleration in a mass of 18 g that moves in a horizontal direction.
F = 36 dyne at an angle of 60° Fₓ = F cos 60° = 18 dyne Fₓ = maₓ So aₓ = Fₓ/m = 1 cm/s²
F = 36 dyne at an angle of 60°
See lessFₓ = F cos 60° = 18 dyne
Fₓ = maₓ
So aₓ = Fₓ/m = 1 cm/s²
