An astronaut is standing on an asteroid when he accidentally drops a wrench. He observes that the gravitational acceleration on the asteroid is 2.4 m/s². If he had thrown the wrench at an upward angle instead, he would have found the gravitational acceleration on the asteroid to be
A block of mass m slides down with uniform speed on an inclined plane having inclination \( \theta \). If the coefficient of friction between the inclined plane and the block is \( \mu \), then the contact force between them is:
