The speed of the object can be calculated using the formula:
Speed = distance/time
The given values are:
distance = 62.43 m
time = 38.4 s
Solution:
speed = 62.43 m / 38.4 s = 1.63 m/s
Therefore, the speed of an object that travels 62.43m in 38.4s is <span> 1.63 m/s.</span>
Answer:
Average speed = 13.5 m/s
Explanation:
Since the car is running at a speed of 27 m/s and it stops after 3 seconds by applying the brake. Therefore, the initial speed of the 27 m/s and final speed is 0.
Use below formula to find the average speed :
Average speed = (Initial speed + final speed ) / 2
Average speed = (27 + 0 ) / 2
Average speed = 13.5 m/s
Choice 1
The Sun's radiation and solar wind cause the dust and gas around the comet (coma) to stretch the coma. The solar wind electromagnetically blows the ions in the coma away.
