Step-by-step explanation:
The type of plane that the block is projected up in question 7938 is
b) Inclined plane
An inclined plane is a flat, sloped surface that allows objects to move up or down with the help of gravitational force. It is commonly used to reduce the force required to move an object vertically. In this case, the block is projected up the inclined plane, indicating that it is moving against gravity.
