Knowing all this and using the answers below, What can you do to save your object?
Think back and reference question 4 and give at least 2 examples and ideas of what you could do to save your object from this fall. (Hint, remember the object is a laptop or phone, so use a logically example like a phone case.)
Given:
V^0 = 0 m/s
a = 9.8 m/s^2
t = 1.5 s
7. To find the velocity after 1.5 seconds have passed, we substitute the values into the equation:
v^1 = v^0 + at
v^1 = 0 + (9.8)(1.5)
v^1 = 0 + 14.7 = 14.7 m/s
8. To calculate the momentum of the object, we need to know the mass of the object (M).
Let's assume the mass of the object is 1 kg (M = 1 kg).
Using the formula P = MV, we can find the momentum:
P = 1 kg * 14.7 m/s = 14.7 kg*m/s
9. To calculate the force with which the object will hit the ground, we again need to know the mass of the object.
Let's assume the mass of the object is 2 kg (M = 2 kg).
Using the formula F = MA, we plug in the values:
F = 2 kg * 9.8 m/s^2 = 19.6 N
So, after 1.5 seconds have passed, the velocity of the object is 14.7 m/s, the momentum is 14.7 kg*m/s, and the force with which it will hit the ground is 19.6 N (assuming a mass of 2 kg).
To save the object from the fall, you can consider the following actions:
1. Using a protective case: One idea is to invest in a durable and shock-absorbent phone or laptop case. This can help cushion the impact and protect the object from damage when it falls. The case should be designed to absorb the force and minimize the transfer of energy to the object, reducing the likelihood of damage.
2. Implementing safety measures: Another idea is to use safety straps or attachments. For example, you can attach a wrist strap or a lanyard to the phone or laptop to ensure that it remains securely fastened to your hand or body. This can prevent accidental drops or falls and save the object from potential damage.
By taking these precautions, you can minimize the impact and protect your object from the fall.
