For every reaction, there is an equal and opposite reaction. This means that with every interaction, theres a pair of opposite forces on the object.

Answer:
32.176 ft/s²
9.807 m/s²
Explanation:
Data provided in the question:
Acceleration of the free falling object = 78979.4 mi/hr²
a) In ft/s
Now,
1 mi = 5280 foot
and,
1 hour = 3600 seconds
thus,
78979.4 mi/hr = 
or
78979.4 mi/hr = 32.176 ft/s² ...............(1)
b) In m/s²
Now,
1 foot = 0.3048 m
thus,
we have from 1
32.17 ft/s² = 
or
78979.4 mi/hr = 32.176 ft/s² = 9.807 m/s²
Answer:
24.4 m
Explanation:
sin 30 = 12.2 / x
x = 12.2 / sin 30 = 24.4 m
Answer:
Option (c).
Explanation:
Let the mass of each cart is m and the force is F.
Time for cart A is 2t and for cart B is t.
Work done is given by the
W= force x displacement
As the distance is given by
S= u t +0.5 at^2
So, when the time is doubled the distance is four times.
So, WA = F x 4 S
WB = F x S
WA= 4 WB
