A bumper car was going 200kph. It took the bumper car 125 seconds to reach that speed. Thr mass was 600cc 100bhp. What is the acceleration and momentum of that bumper car
To find the acceleration of the bumper car, we can use the formula:
Acceleration = (final velocity - initial velocity) / time
Given:
Initial velocity (u) = 0 (since the car starts from rest)
Final velocity (v) = 200 kph = (200 * 1000) / 3600 m/s = 55.56 m/s
Time (t) = 125 seconds
Acceleration = (55.56 - 0) / 125 = 0.445 m/s²
To calculate the momentum of the bumper car, we use the formula:
Momentum = Mass * Velocity
Given:
Mass = 600 cc = 600 cm³
We need to convert it to kg.
1 cm³ = 1 gram
1 kg = 1000 grams
Mass = 600 cm³ * (1 gram / 1 cm³) * (1 kg / 1000 grams) = 0.6 kg
Momentum = 0.6 kg * 55.56 m/s = 33.336 kg·m/s
Therefore, the acceleration of the bumper car is 0.445 m/s², and its momentum is 33.336 kg·m/s.
