Question

1 a mass of 6kg is taken from the ground height of 100m find the potential energy of an object g = 9.8 m/s ^ 2

2 a cyclist and bike have a total mass of 110kg and the speed is 18m/s. calculate the kinetic energy

Answer 1

1)5880 J

2)17,820

Step-by-step explanation:

1) PE=mgh

=6×9.8×100

=5880 J

2)Ke=1/2mv^2

=1/2×110×18^2

=17,820 J
