Ответ:
10km/hr
Explanation:
Speed = distance/time
time=1/2 hour
distance=5km
5/(1/2) multiplied by 2 = 10km/1hr = 10km per hour
Ответ:
momentum = mass × velocity
momentum before collision = (0.0010×5)+(0.35×0)=0.05
momentum after collision = 0.05
mass after collision (0.0010+0.35)= 0.351 kg
velocity after collision = 0.05/0.351=0.142 m/s
