By Newton's second law, we have

So, in order to give a 0.15kg body an acceleration of 40m/s^2, you need a force of

Answer:

Explanation:
From the question we are told that:
Weight 
Altitude
Let
Radius of Earth 
Gravity 
Generally the equation for Gravity at altitude is mathematically given by


Therefore
Weight at sea level


Weight at 6.33 altitude


Therefore



D , since Voltage is one joule per coulomb
In a completely inelastic collision, the two objects stick together after the collision.
