Answer:
The Moon rotating around Earth and the Earth rotating around the Sun
Explanation:
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.
The Newton's Laws that BEST describe the situation is Newton's second law of motion.
<h3>
What is Newton's second law of motion?</h3>
Newton's second law of motion states, the force exerted by an object is directly proportional to the product of mass and acceleration of the object.
Also, the law can also be states as force is equal to the rate of change of momentum.
F ∝ Δp
Ft = m(v2 - v1)
The force exerted on the bicyclist by the fence is equal to the change in momentum of the bicyclist. The bicyclist was able to fly over the fence because there is a change in his momentum.
Thus, the Newton's Laws that BEST describe the situation is Newton's second law of motion.
