You can write this equal and opposite vector by flipping the sign, or by reversing the direction, like this: the velocity of the ground relative to you = = -8 km/hr west = 8 km/hr east The velocity of the train relative to you, , can be found by adding vectors appropriately. A child’s swing is held up by two ropes tied to a tree branch that hangs 13.0° from the vertical. The antipodal city to Las Piedras is Changtu. TI-Nspire CAS tip When solving problems in trigonometry, your calculator should be kept in Degree mode. A car is driven east for a distance of 88 km, then north for 28 km, then in a direction 30 degrees east of north for 25 km. must be equal and opposite. The instructions read to first sail 27.5 m in a direction 66.0º north of east from her current location, and then travel 30.0 m in a direction 112º north of east (or 22.0º west of north). They are separated by 5km . Example 2: Sowmya Krishnan walked 20 m towards the north. Momentum = (mass-1)x(v1_initial northward) + (mass-2)x(v2_initial northward) Momentum = (1500-kg)x(0 km/h) + (3000-kg)x(-60.0 km/h) = -180,000 kg km /h. tan 30 = opposite adjacent is always 1 √ 3 = 0.5774 (to 4 decimal places). The second plane starts 0.5 hours after the first plane, but it's speed is 80 km/hr faster. 6.0 km 8. Opposite side in the world. Distance = 3 km + 4 km = 7 km For the displacement, we will use the Pythagorean Theorem because David’s path makes a right angle. … Let the computer write the numbers. D is S80ºW from O..
