Answer:
D.
Step-by-step explanation:
Momentum(p) is Mass(m) times Velocity(v) or p = mv
The results of the calculations are attached. 0.4 kg at 2 m/s has the most momentum: 0.8 kg*m/s
The answer is A
It is A because you multiply by the slope
The answer is D. say you have 21 split into 5 parts then you will have 5 4.2's. then take three of them and you get 12.6.
The distance travelled by the car will be 3.6km in 2 minutes.
<u>Explanation:</u>
Given:
Speed, s = 108 km/hr
s in km/min = ?
1 hr = 60 min
So,
108 km/hr = 
= 1.8 km/min
time, t = 2 min
Distance, d = ?
We know:
distance = speed X time

Therefore, the distance travelled by the car will be 3.6km in 2 minutes.
