AI Thread Summary
To calculate the speed and momentum of a T. rex, the time between footprints (0.62 seconds) and the distance between them (10 meters) can be used to determine speed. Given that speed is constant, the formula v = d/t can be applied, where d is distance and t is time. This results in a calculated speed of approximately 16.13 m/s, which is higher than the suggested maximum speed of 8 m/s. The mass of the T. rex (7000 kg) can then be used to calculate momentum using the formula p = mv, where p is momentum, m is mass, and v is speed. Understanding these calculations is essential to accurately represent the T. rex's speed and momentum.

Homework Statement



calculate speed and momentum of T REX. Time between footprints is 0.62s - there are 2 footprints in a 10m distance, speed is constant - I need to show that the maximum speed is about 8ms-1 - how to I go about doing this? Help I have no idea
Its mass is 7000kg.

Homework Equations



v=u+at


The Attempt at a Solution



8ms-1 = 0 + at but time is what time between footprints is only known time?

They tell you that the speed is constant. Knowing this, can you use the time given and the distances given to find v? What formulas for v apply when v is constant?
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
