Answer:
2687.7 N
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
When he will reach the ground his speed will be 3.2 m/s but will travel 30 cm down
Force
The force on the legs will be 2687.7 N
Answer:
The relation between SI and CGS unit of force is the CGS unit of force is equal to SI unit of force. The force is the product of mass and acceleration. its SI unit is Newton and CGS unit is dyne. The relation between SI and CGS unit of force is.

Answer:
0.903 seconds
Explanation:
To find how many seconds the acorn fall, we can use the formula for distance travelled with constant acceleration:
D = Vo*t + a*t^2/2,
where D is the distance travelled, Vo is the inicial speed, t is the time and a is the acceleration.
In our problem:
Vo = 0,
a = g = 9.81 m/s2,
D = 4 meters.
So, we can solve the equation to find the time:
4 = 0*t +9.81*t^2/2
4.905*t^2 = 4
t^2 = 4/4.905 = 0.8155
t = 0.903 seconds
