Answer:
(i) Relative velocity of B w.r.t A= Sum of speeds of trains
=54+90
=144kmph
(ii)Relative velocity of B w.r.t Ground(G)=v
B/G
=−90kmph
v
G
=0
Relative velocity of ground(G) w.r.t B =v
G/B
=v
G
−v
B/G
v
G/B
=0−(−90)
v
G/B
=90kmph

The magnitude of the acceleration is 0.1038 m/s²
Explanation:
Net force is given by the square root of the sum of squares of the forces in y and x coordinates
Absolute Net Force will be;
However, Fnet can be calculated as the product of force and acceleration
Fnet=m*a
Fnet= 80.45 N
m= 775 kg
a=?
80.45=775*a
80.45/775= a
0.1038 m/s²=a

Answer:
<u>Gravitational Force</u> is a force that attracks two objects with mass. For example, you are being pulled onto this planet, and that's why when you jump upwards, you fall back down quickly. A fun fact is that every object, even the entire universe, are pulling all on each other, including you!
