The speed of a car weighing 1500kg increase from 40m/s to 50m/s.calculate the change in its momentum
Your School SUBJECT is probably PHYSICS.
well, the momentum has changed from
1500*40 to 1500*50
How hard is that?
Yes
To calculate the change in momentum, you need to find the initial momentum and the final momentum of the car.
Momentum (p) is given by the formula:
p = mass * velocity
Initial momentum (p1) can be calculated as:
p1 = mass * initial velocity
Final momentum (p2) can be calculated as:
p2 = mass * final velocity
The change in momentum (Δp) can be found by subtracting the initial momentum from the final momentum:
Δp = p2 - p1
Given:
Mass (m) = 1500 kg
Initial velocity (v1) = 40 m/s
Final velocity (v2) = 50 m/s
Calculating p1:
p1 = m * v1
p1 = 1500 kg * 40 m/s
Calculating p2:
p2 = m * v2
p2 = 1500 kg * 50 m/s
Calculating Δp:
Δp = p2 - p1
Now, let's calculate the change in momentum:
p1 = 1500 kg * 40 m/s = 60000 kg*m/s
p2 = 1500 kg * 50 m/s = 75000 kg*m/s
Δp = p2 - p1
= 75000 kg*m/s - 60000 kg*m/s
= 15000 kg*m/s
Therefore, the change in momentum of the car is 15000 kg*m/s.
