Answer:
Force, F = 2356.19 N
Explanation:
Given that,
Diameter of the circular tip, d = 1 mm = 0.001 m
Its radius, r = 0.0005 m
Pressure created, 
To find,
Force exerted on the nail.
Solution,
The pressure exerted by an object is equal to the force acting per unit area. Its formula is given by :
F = 2356.19 N
Therefore, the force exerted on the nail is 2356.19 N.
Answer:
the ball will go up 3s and down 3s
v=gt
where t=3s and g=9.8m/s^2
distance=v0(t)+(1/2)gt^2
where initial velocity (v0)=0
