during a race,a dragster is 200 meters from the finish line when something goes wrong and its stops accelerating.it travels at a constant velocity of45 meters per second for 3seconds to try to finish the race.How far from the finish line is the dragster after 3 seconds?
65m
You kidding?
200 - 3(45)
To find the distance from the finish line after 3 seconds, we need to calculate the distance covered during the constant velocity phase.
The formula to calculate distance is:
Distance = Velocity x Time
Given that the dragster travels at a constant velocity of 45 meters per second for 3 seconds, we can substitute these values into the formula:
Distance = 45 m/s x 3 s
Distance = 135 meters
Therefore, the dragster is 135 meters from the finish line after 3 seconds.
To find the distance from the finish line after 3 seconds, we can use the formula:
Distance = Initial Distance + Velocity × Time
The initial distance from the finish line is given as 200 meters. The velocity is constant at 45 meters per second, and the time is 3 seconds.
Let's substitute these values into the formula and calculate the distance:
Distance = 200 meters + (45 meters/second) × 3 seconds
Distance = 200 meters + 135 meters
Distance = 335 meters
Therefore, after 3 seconds, the dragster is 335 meters from the finish line.
