Answer:
333 N
Explanation:
The weight of an object is given by:

where
m is the mass of the object
g is the acceleration of gravity
For the mower in the problem,
m = 34 kg
Also

So, the weight of the mower is

Answer:
3. Higher in some places and lower in other places
Explanation:
speed of curved path=under root of Mew and gravity
smooth surface Mew=0
so under root of 0×g
=0
Here in order to find out the distance between two planes after 3 hours can be calculated by the concept of relative velocity

here
speed of first plane is 700 mi/h at 31.3 degree


speed of second plane is 570 mi/h at 134 degree


now the relative velocity is given as


now the distance between them is given as



so the magnitude of the distance is given as

miles
so the distance between them is 2985.6 miles
