False
we can calculate it at a specific time by taking the derivative of positive function, which gives us the functional form of instantaneous velocity v(t)
Answer: Gravity will be on you since you are falling. For instance if you where skydiving you are free falling which will be similar to the car. Therefore gravity does play a role because whatever goes up must come down.
Explanation:
Answer:
748.8 kJ
Explanation:
Kinetic energy is given by
where m is the mass of the body, v is the velocity
Substituting 2600 Kg for m and 24 m/s for velocity
Therefore, kinetic energy is 748.8 kJ
Answer:
n = 1.76
Explanation:
According to the rule of ( n1 sin theta1 = n2 sin theta2 )
we know both angles so we insert them to the law and apply n1 = 1
so 1/2 = n2 sin 62 and we get the final answer
