Question

A 3000kg truck increases its velocity from 10m/s to 25m/s. What is the change of momentum?

Answer 1

45000 Kg.m/s

Step-by-step explanation:

change in momentum = m( v¹-vi)

=3000(25-10)

= 45000

Answer 2

45000Kgms is the required change in momentum .

Step-by-step explanation:

As Per given Question

Mass of truck m = 3000Kg

Initial velocity u = 10m/s

Final velocity v = 25m/s

Calculating the change in velocity

→∆v = 25 - 10

→ ∆v = 15m/s

`\bf \Delta \: p = m (\Delta\:v)`

On substituting the value we get

`\implies\bf \Delta \: p = 3000 * (15) \\ \\ \implies\bf \Delta \: p = 45000kgm {s}^{}`

So, the change in momentum is 45000Kgms
