Question

plz anwer 4th question

Answer 1

zero is the answer as velocity at the highest point is zero no influence of power will be at that point

Answer 2

Hey there !!..

Let particle velocity u = 10 m/s is thrown at an angle 37°



●--------> ucos 37°
|
|
v
mg

here we know that velocity at Highest point is ucos 37 and we can see that angle between force and velocity is 90°


=) power(P) = F.v

=) P = Fvcos90

therefore , P = 0

so power delivered at Highest point is zero ,
