Answer:
Centripetal force comes from the Latin, centrum = centre and petere=to seek. It acts perpendicular to the object path, towards the center of the curve. This results in change of the direction of the object's velocity but not in change of object's speed.
So only the first option is correct: It acts at a right angle to the object's motion and causes the object to constantly change direction.

Answer:
The time it will take the mega-ray blaster to hit the ground is 2.57 s.
Explanation:
Given;
initial velocity of Optimus Prime, u = 24 m/s
height of fall of the mega-ray blaster, h = 94 m
The time of fall of the mega-ray blaster is calculated using the following kinematic equation;


t = 2.57 s
Therefore, the time it will take the mega-ray blaster to hit the ground is 2.57 s.
