Yes, if the object is larger. while a solid block of iron will have a greater mass than a block of aluminum of the same size, a much larger block of aluminum can have greater mass than the smaller block of iron.
By how much would its speed reading increase with each second of fall? ... Ex 3.24 For a freely falling object dropped from rest, what is its acceleration at the end of the 5th second ... Pb 3.3 A ball is thrown straight up with an initial speed of 30 m/s. How high does it go, and how long is it in the air (neglecting air resistance)?.
Answer:
2 m/s
Explanation:
Given that a student walks 4 blocks east, 1 blocks north, 2 block west and then 1 blocks south in an hour.
The total time = 1 hour
The vertical displacement = 1 - 1
Vertical displacement = 0
Horizontal displacement = 4 - 2
Horizontal displacement = 2
Total displacement = sqrt (2^2 - 0^2)
Total Displacement = 2
Average velocity = displacement/time
average velocity = 2 / 1
Average velocity = 2 m/s
Therefore, her average velocity is 2 metres per second.
Answer:
25 m/s
Explanation:
1 km/h = .277778 m/s, so 90 x .277778 = 25
