A palm fruit dropped to the ground from the top of a tree 45m tall. How long does it take to reach the ground?
(Take g = 10m/s²)
ANSWER: Option E
EXPLANATION: using the equation of the motion S = ut + ½gt² and making time taken t the subject of the formula.
Where in this case:
S –> the height of the tree
u –> the initial velocity which in this case is zero
t –> time take to reach the ground
g –> acceleration due to gravity
