Question

A car of mass 1500kg travels with a speed of 10m/s. The driver applies break and it stops after 5 seconds. Calculate initial and final momentum of the car.( dont cheat me if you cheat me I will repot you)​

Answer 1

Answer:

hope this will surely help u

Answer 2

$\underline{ \sf \large{Solution- }}$

Here it is given that,

• Mass (m) = 1500 kg
• Initial velocity (u) = 10 m/s
• Final velocity (v) = 0 m/s
• Time (t) = 5 seconds

➢ We have to find the initial and final momentum of the car.

We know that,

• Momentum (p) = Mass × Velocity

Now,

For the initial momentum of car :

⟹ Initial momentum = Mass × initial velocity

⟹ Initial momentum = 1500 × 10

⟹ Initial momentum = 15000 kg.m/s

Now,

For the final momentum of car :

⟹ Final momentum = Mass × final velocity

⟹ Final momentum = 1500 × 0

⟹ Final momentum = 0 kg.m/s
