Well you could see it's physical properties have the same descriptions corresponding to a liquid. (Sorry if this doesn't help you..)
Answer:
Va = 5000 m / 3600 s = 1.39 m/s
(Va - Vb) 60 = 10
Vb = Va - .167 = 1.22 m/s
(Va - Vb) T = 4200 Π where T is time for A to complete 1 more lap
.17 T = 4200 Π
T = 24700 Π time for A to again catch B
N = 1.39 * 24700 Answer:
Va = 5000 m / 3600 s = 1.39 m/s
(Va - Vb) 60 = 10
Vb = Va - .167 = 1.22 m/s
(Va - Vb) T = 4200 Π where T is time for A to complete 1 more lap
.17 T = 4200 Π
T = 24700 Π time for A to again catch B
N = 1.39 * 24700 Π / (4200 Π) = 8.2 laps
A will make 8 but not 9 rounds before catching B
Answer:
133 kg
Explanation:
Parameters given:
Mass of tackler, m = 133 kg
Initial velocity of tackler, u = 3.4 m/s
Final velocity of tackler and receiver, v = 1.7 m/s
Since momentum is conserved, we apply the principle of conservation of momentum:
Total initial momentum = Total final momentum
mu + MU = (m + M)v
Where U = initial velocity of receiver = 0 m/s
M = mass of receiver
Therefore:
(133 * 3.4) + (M * 0) = (133 + M) * 1.7
452.2 = (133 + M) * 1.7
(133 + M) = 452.2/1.7
133 + M = 266
=> M = 266 - 133
M = 133 kg
The mass of the receiver is 133 kg.
