Which of the following would have less momentum than a 52 kg cheetah running at 10 m/s?
A. A 71 kg lion running at 10 m/s.
B. A 45 kg zebra running at 13 m/s.
C. A 5,000 kg elephant walking at 1 m/s.
D. A 61 kg zebra running at 8.0 m/s.
Is the answer C?
Thank you
answer is B
the answer is NOT B, it is D, Maleik is lying
which is it ??? D or C
It is D but why tho?
The answer is c: 61 kg zebra running at 8m/s the way you calculate the momentum is by multiplying the weight times the time: 61x8=488 which is the only one less than 52 kg cheetah running at 10 m/s: 52x10=520
To determine which object has less momentum than the 52 kg cheetah running at 10 m/s, we need to calculate the momentum of each object and compare them.
The formula for momentum is:
momentum = mass × velocity
Let's calculate the momentum for each object:
A. Momentum of the 71 kg lion running at 10 m/s:
momentum = 71 kg × 10 m/s = 710 kg·m/s
B. Momentum of the 45 kg zebra running at 13 m/s:
momentum = 45 kg × 13 m/s = 585 kg·m/s
C. Momentum of the 5,000 kg elephant walking at 1 m/s:
momentum = 5,000 kg × 1 m/s = 5,000 kg·m/s
D. Momentum of the 61 kg zebra running at 8.0 m/s:
momentum = 61 kg × 8.0 m/s = 488 kg·m/s
Comparing the calculated momentum values, we can see that the momentum of the 5,000 kg elephant walking at 1 m/s is the highest among the given options. Therefore, option C (A 5,000 kg elephant walking at 1 m/s) does not have less momentum than the cheetah.
The correct answer is D (A 61 kg zebra running at 8.0 m/s), as it has a lower momentum (488 kg·m/s) than the cheetah.
