Answer:
less than 20580 N
Explanation:
According to the newton's second law of motion
Force = mass * acceleration
(assuming gravitational acceleration =9.8 m/s2 )
acceleration = 30*9.8 = 294 m/s2
acting Force = 70 * 294
= 20580 N
Since the acceleration was less than 30g , acting force should also be less than 20580 N
Answer:
Explanation:
From the question we are told that:
Force 
Time 
Length of pedal 
Radius of wheel 
Moment of inertia, 
Generally the equation for Torque on pedal 
is mathematically given by
Generally the equation for angular acceleration 
is mathematically given by
Therefore Angular speed is \omega
Generally the equation for Tangential velocity V is mathematically given by
Answer:
The higher the spring constant, the greater the elastic potential energy.
