Answer:
Explanation:
= Mass of ball = 0.12 kg
tex]m_{2}[/tex] = Mass of bottle = 2.4 kg
= Initial velocity of ball
= Initial velocity of bottle
= Final velocity of ball =
= Final velocity of bottle
As linear momentum is conserved
The bottle's speed is
R = 1.5 m , m = 0.05 kg
Tension = Centrifugal force
T= mrw² , w = angular velocity
3.3 N = 0.05 x 1.5 x w²
w = 6.63 rps
Linear Velocity = rw = 1.5 x 6.63 = 9.945 m/s
Answer:
According to Newton's first law of motion, an object maintains its state unless a force acts on it. Therefore, a moving car does not change its direction and keeps its speed unless a force acts on it.
It is C, gasses with less kinetic energy, i did this and i think i remember it was C
