Question

The value of acceleration due to gravity is 980 cm /s-2 what will be its vvalue if unit of length is km and time is minute​

Answer 1

1,00,000cm=1km

1cm =1/1,00,000 km

Now,

60 seconds = 1 min

1 second = 1/60 min

Now,

980cm/ second^2 can be written as =980/1,00,000 * (60)^2 /1

=980/1,00,000 * (3600)

=35.28 KM/min^2

Answer 2

Answer:  The answer is  $35.28 km/min2$

Explanation:

$g=980cm/s^2\\1cm= 1/10^5km\\1s=1/60ming=980*10^-5*(60)*(60)km/min^2 \\g=35.28km/min 2$

Gravitational Acceleration: What Is It?

• Acceleration owing to gravity is the term used to describe the acceleration that a body feels as a result of gravitational force.
• Its SI unit is M/s2. It qualifies as a quantity because of its vector nature, which contains both magnitude and direction.
• The gravitational acceleration unit is g.
• The standard value of g on the surface of the earth is 9.8 m/s2 at sea level.
• Acceleration and velocity both occur within the context of time.
• The velocity or acceleration of an object determines how far it will travel in a certain amount of time.
• Get a handle on velocity first.
• The rate of change of an object's displacement over time is known as its velocity because it is a vector and can, thus, take a negative value.
• "How much this object has moved (and in what direction) in a specified time frame" is the only definition given.
