courts have many properties including Mass electric charge and color their Mass tells you something about how much matter they are made of or how heavy they would be if you could wear them up charm and top quarks have a positive 2/3 charge
Answer:
D
Explanation:
you can catch it, rolling against a surface can slow it and when you throw it in the air, gravity will slow it down until it drops
Answer:
V = -1.33 m/s
Explanation:
Given,
The mass of the camper, m = 100 kg
The velocity of the camper, v = 3.0 m/s
The combined mass of canoe and another camper, M = 225 kg
The velocity of the combined canoe and another camper, V = ?
According to the law of conservation of momentum,
MV + mv = 0 (Since the initial momentum of the dock is 0)
V = -mv/M
= -100 x 3/225
= -1.33 m/s
The negative sign indicates that the combined objects moves opposite to that of the camper.
Hence, the velocity of the combined canoe and camper is, V = -1.33 m/s
