Explanation:
The weight of a body depends on the acceleration due to gravity at a particular place.
Weight is a form of force on a body but this type depends on the gravitational force from places to places.
Weight = mass x acceleration due to gravity.
Assuming that mass is constant, the acceleration due to gravity is directly proportional to the weight.
The higher the acceleration due to gravity of a body, the more it weighs and vice - versa.
Answer:v=142.85 mph
Explanation:
Given
Distance between two cities is 1000 miles
Speed of plane 1 id 250 mph
Plane 1 leaves at 7 am and Plane 2 leaves at 7:30 am
They will collide if plane 2 travels 300 miles and Plane 1 travels 400 miles in t and t+0.5 hr respectively
Time taken by plane 2
----1
time taken by plane 1 to travel 400 miles
-----2
substitute value of t in 2
