A parachutise jumps out from an airplace. What is his acceleration?
0 m/s2 because air resistance is negligible
10 m/s2 because air resistance is negligible so acceleration = acceleration due to gravity
0 m/s2 because gravitational force has not acted on him
10 m/s2 because gravitational force has not acted on him so acceleration = acceleration due to gravity

Coconut 1 has a weight of 5 N and Coconut 2 has a weight of 2 N. Both falls at the same time from the same height. Which coconut will reach the ground first and why?
Coconut 1 because it has more gravitational force acting on it
Coconut 2 because it has lesser weight
Both will reach the ground first as air resistance is negligible so they fall under same acceleration due to gravity
Coconut 2 because it has less surface area hence experience less air resistance
