Acharged object traveling 7 m in a uniform electric field of 5 n/c experiences a 4 j increase in kinetic energy.

if the distance remains the same and the electric field is increased to 40. n/c, then what will be the kinetic energy change of the charged object?

How many seconds does it take a pebble released from rest off a bridge to fall 29.4 m ? what is the pebble's speed when it has fallen 29.4 m ?
