Question

Would any one of the below two cases require a greater force?Justify your answer. accelerating a 20g mass at 5m/s2 or a 25g mass at 4m/s2​

Answer 1

Answer:

let us split this question into 2 cases

CASE 1

Mass (m) = 20 g = 0.02 kg

Accleration (a) = 5 m/s²

so Force (F) = ?

F = ma

= F = 0.02 x 5

= F = 0.1 N

SO THE FORCE IS CASE 1 IS 0.1 N

CASE 2

Mass (m) = 0.025

Accleration (a) = 4 m/s²

Force (F) = ?

F = ma

= F = 0.025 X 4

= F = 0.1

SO THE FORCE IN CASE 2 IS 0.1 N

SO THE FORCES IN CASE 1 = CASE 2

SO BOTH THE CASES HAVE EQUAL FORCES THAT IS 0.1 N
