Question

an object mass 25 kg is placed in rest then 100 n force applied at object for 20 second then determine acceleration of object and change in momentum of object ?

Answer 1

F = ma

100 = 25 a

a = 100/25

a = 4 ms⁻²

v = u + at = 0 + 4(20) = 80 ms⁻¹

p = m v = 25 x 80 = 2000

Answer 2

Answer:

Explanation:F = ma

100 = 25 a

a = 100/25

a = 4 ms⁻²

v = u + at = 0 + 4(20) = 80 ms⁻¹

p = m v = 25 x 80 = 2000
