Answer:
Explanation:
To solve this problem, we can use the following suvat equation:
where
is the vertical displacement of the frog
is the initial vertical velocity
t is the time
a is the acceleration
We have chosen this formula because apart from , all the other quantities are known. In fact:
is the vertical displacement
t = 2 s is the total time of flight
is the acceleration due to gravity (negative because it is downward)
Therefore, solving for , we find the initial velocity of the frog:
Answer: 1.274 N minimum force required to slide the book across the surface
Explanation:
Mass of the book = m = 0.2 kg
Normal force acting on the book,N = mg
Coefficient of friction = = 0.65
Minimum force required to slide the book across the surface= F
1.274 N minimum force required to slide the book across the surface
