Arubbit gets down from a rump which its /\x=0.85m in 0.5s, the rubbit's mass is 2kg, what is the net force?

13.6 N

Explanation:

The equation of motion for the rabbit is:

(1)

Where:

is the distance traveled by the rabbit

is the rabbit's initial velocity, assuming it started from rest

is the time

is the acceleration

Isolating :

(2)

(3)

(4)

On the other hand, the force is given by:

(5)

Where is the mass of the rabbit

Substituting (4) in (5):

(6)

Finally:

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
