A rugby player of mass 75 kg, running east at 8.0 m/s, tackles another player of mass 90 kg who is running directly towards him

at 5.0 m/s. If the two players cling together after the tackle, what will be their common velocity?

You can use the formula:
(m1 + m2)vf = m1vi
m1 = mass of first rugby player (75 kg)
m2 = mass of second rugby player (90)
vf = their final velocity
vi = the initial velocity 

(m1 + m2)vf = m1vi
(75 + 90)vf = (75)(8.0)
165(vf) = 600
        vf = 3.64 m/s

hope this helps :)

Find the hiker’s gravitational potential energy if the cliff is 60m high
Furkat [3]

Answer:

Potential energy is U=mgh

Explanation:

The potential energy depends on the mass, the acceleration of gravity g and the height at which the object or person is.

Potential energy  U=mgh

In this case we would need to know the exact mass of the hiker in order to calculate the potential energy.

But we know the values of g and h

g=9.81m/s^2

h=60m

So, the potential energy

U=m(9.81m/s^2)(60m)\\\\U=588.6*m

m is the mass of the hiker, wich is not in the description of the problem.

Describe free fall and weightlessness ?<br>​
yaroslaw [1]

weightlessness is the complete or near complete absense of the sensation of weight.

when in freefall,the only force acting upon your body is the force of gravity a noun contact force.since the gravity cannot be felt without any other opposing forces,you would have no sensation of it.you would feel weightless when in a state of freefall.
