<h3><u>Answer;</u></h3>
126 joules
<h3><u>Explanation;</u></h3>
Potential energy is the energy possessed by a body while at rest.
It is calculated by the formula m×g×h; where m is the mass, h is the height and g is the gravitational acceleration, 10N/kg
Potential energy = m×g×h
= 3.0 × 4.2 × 10
<u>= 126 joules</u>

Answer:
A: 15 m/s
B: 900 Meters
Explanation:
A. Average speed is equal to final velocity plus initial velocity divided by two
Va= (20+10)/2 = 15 m/s
B.
distance = speed × time
D= 15 m/s * 60s = 900 Meters
