Mass doesn't depend on anything else that's around you, but weight does.

The astronaut's mass is still 65 kilograms, on the moon or wherever else
she may go.

But on the moon, her weight is only 105 newtons.

The mass of the astronaut is still 65 kilograms. Mass is constant or doesn't change no matter where you are.

A lion has a mass of 45 kg. Answer the following questions about it, using correct units. a. The lion runs at a speed of 14.2 m/
Eva8 [605]
A) The kinetic energy of an object is given by:
K= \frac{1}{2}mv^2
where m is the mass of the object, and v its speed. For the lion in our problem, m=45 kg and v=14.2 m/s, so its kinetic energy is
K= \frac{1}{2}mv^2= \frac{1}{2}(45 kg)(14.2 m/s)^2=4537 J

b) the increase in gravitational potential energy of the lion is given by:
\Delta U = mg \Delta h
where g is the gravitational acceleration, and \Delta h is the increase in altitude of the lion. In this problem, \Delta h=28 m, so the increase in gravitational potential energy is
\Delta U=mg \Delta h=(45 kg)(9.81 m/s^2)(28 m)=12361 J

c) When the fox reaches the top of the tree, its gravitational potential energy is
U=mgh=(1.8 kg)(9.81 m/s^2)(3.8 m)=67 J
As it jumps, its kinetic energy is
K= \frac{1}{2}mv^2= \frac{1}{2}(1.8 kg)(8.1 m/s)^2=59 J
So the total mechanical energy of the fox as it jumps is
E=U+K=67 J + 59 J =126 J

A person jogs for 4.0 km in 32 mins,then 2.0km in 22mins,and finallu 1.0 km in 16 mins.whqt is the joggers average speed in km p
blondinia [14]

Average speed = (total distance covered) / (time to cover the distance)

total distance covered = (4km + 2km + 1km) = 7 km

time to cover the distance = (32min + 22min + 16min) = 70 min

Average speed = (7 km) / (70 min)

Average speed = 0.1 km/minute
