Answer:

Explanation:

Work done is expressed as;

Work done = Force × distance

Given

Force = 1400N

Distance = 0.3m

Workdone = 1400×0.3

Work done = 420joules

Given mass = 70kg

Weight = 700N

To know how high you will ride into the air

420 = 700×d

d = 420/700

d = 0.6m

You ride 0.6m into the air
