please help me answers these ones two

Complete the table by finding the acceleration for each item. Some of your answers might be negative numbers. They express deceleration in terms of negative acceleration. The first one is done for you. Theory of Relativity Albert Einstein proposed his special theory of relativity. A main idea in Einstein's novolves the speed of light. Einstein said that light always travels at the same d that nothing travels faster than light. The measurement of the speed of light anges. showed that time and space could not be considered separately. He concluded re and time change when things move near the speed of light. Metersticks space; clocks measure time. At very high speeds, clocks slow down and iks get shorter. Measuring length and time depends on the object's speed o the measurer's speed. This is because measurement of the speed of light constant. conclusions shocked other physicists and still are challenging to understand. le, we do not see length and time change with speed. But we also do not move close to the speed of light. Einstein's ideas have been proven mathematically real world. They have changed the way scientists view the universe
