Can someone help with part b? Please provide an explanation for it.
O1: Rick and Morty
mark: 1 point for each part
In Rick and Morty, Rick opens a portal and tries to throw his gun directly upwards with a velocity of 2 m/s, as shown in the picture. The acceleration due to gravity is 10 m/s^2.
a) What is the instantaneous velocity and acceleration of the gun at the highest point of its trajectory? Explain your answer.
v = 0 m/s, a = -10 m/s^2
b) Assume the gun can't get to the portal at the top. What will be the final velocity v of the gun just before it gets into the portal at the bottom? Explain your answer. (Neglect air resistance.)
v = -2 m/s
c) If a is the acceleration of the gun, and v is its velocity, which statement is true for when the gun reaches the highest point of its trajectory? Explain your answer.
B. Only v is zero and a is not.
d) What will be the maximum height it will reach and when will it be?
A. 0.2 m, 2 s
