An object with a mass of 1.5kg changes its velocity from + 15m/s to + 22 during a time interval of 3.5 seconds. What Impulse was delivered to the object A: 3.0 N•s B: 11 N•s C: 25 N•s D: 56 N•s

In an attempt to reduce the extraordinary long travel times for voyaging to distant stars, some people have suggested traveling close to the speed of light.

One might imagine that if energy generation by nuclear fusion were to increase in a star, this would heat the gas, which would in turn increase the rate of nuclear fusion, and so forth in a runaway cycle of increasing temperature.

The table represents the speed of a car in a northern direction over several seconds. A 2-column table with 5 rows. The first column labeled Column 1 has entries 0, 2, 4, 6, 8, 10. The second column labeled Column 2 has entries 5, 10, 15, 20, 25, 30.
