The energy would remain equal to that of the initial kinetic energy since it is a frictionless surface. However if it is an inelastic collision then energy would be lost due to sound and heat.
Answer: the same number of decimal places as the least precise value.
Explanation:
Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
The rule apply for the addition and subtraction is :
The least precise number present after the decimal point determines the number of significant figures in the answer.
For example: 12.1 + 3.245 = 15.3 as the least precise number 12.1 has one decimal place.
Thus William should write the sum of these two numbers by using the same number of decimal places as the least precise value.

The girl on the right thinks that being on the moon changes your mass, but this is inaccurate. Your mass stays the same, regardless of where you are, but your acceleration (weight) changes if you go to the moon.

Explanation:
Linear acceleration is a type of acceleration of a body along a straight path or line.
Acceleration is defined as the rate of change of velocity with time.
Acceleration = 
There are different types of acceleration .
- linear acceleration is used to describe the rate of change of velocity of a body along a straight path with time.
- centripetal acceleration is the rate of change of velocity of a body traveling along a circular path with time. It is directed towards the center.
- Angular acceleration is the rate of change of angular velocity.
