BRENZ EDUARD C, ILAGAN A ship being launched slides down the ways with a constant acceleration. It takes four seconds to slide the first meter. How long will it take to slide down the ways if their length is 900m Answer 2min DYNAMICS OF RIGID BODIES | ENGR. BRENZ EDUARD C, ILAGAN A driver traveling at 50mph sees a wall at a certain distance ahead. The driver applies the brake immediately (perception time is 3 seconds) and begins to slowing the vehicle at 6m/sec2. If the distance from the stopping point to the wall is 12m. How far was the car from the wall upon perception? Answer 120.74m DYNAMICS OF RIGID BODIES | ENGR. BRENZ EDUARD C, ILAGAN FREE FALLING BODY Freefall is a common kind of motion which everybody can observe in daily life. If we drop something accidentally we can see its motion. In the beginning, it will have low speed and until the end, it gains speed and before the collision, it reaches its maximum speed. Many factors are there to affect the speed of the object while it is in free fall. DYNAMICS OF RIGID BODIES | ENGR. BRENZ EDUARD C, ILAGAN Answer: 5 seconds, 400ft, DYNAMICS OF RIGID BODIES | ENGR. BRENZ EDUARD C, ILAGAN Suppose that you throw a ball straight up at 10m/s and release it at 2m above the ground. A.) What maximum height above the ground does the ball reach? B.) How long after you release it des the ball hits the ground? C.) What is the magnitude of its velocity just before it hits the ground? Answer 7.1m, 2.22sec, 11.8m/s DYNAMICS OF RIGID BODIES | ENGR. BRENZ EDUARD C, ILAGAN A stone was dropped from a balloon which is ascending at a rate of 6m/s when the balloon was 70m above the ground. A.) Which of the following gives the velocity of the stone after 3 seconds? B.) Which of the following gives the time required for the stone attain a downward velocity of 15m/s? C.) How far the stone was from the ground after 4 seconds.? D.) How long did it take the stone to hit the ground? Answer 23.43, 2.14sec, 54.48, 4.44sec DYNAMICS OF RIGID BODIES | ENGR.
