Answer:
<h2>19,600 J</h2>
Step-by-step explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
We have
PE = 500 × 9.8 × 4
We have the final answer as
<h3>19,600 J</h3>

Answer:
The velocity in meter per seconds is 76.9m/s
Step-by-step explanation:
The total distance walked is 1000m
Velocity= distance/time
= 1000/13
= 76.9m/s
The speed and velocity is used interchangeably therefore the speed is also 76.9 m/s
Answer:
a) x = 3.0625m
y = 45.9375 m
b) A = 140.68359375 m²
Step-by-step explanation:
Let x be the length
Let y be the width
2x + 2y = 98
x + y = 49
y = 3(5x)
y = 15x
x + 15x = 49
16x = 49
x = 3.0625 m
y = 15(3.0625) = 45.9375
A = xy = 3.0625(45.9375) = 140.68359375
