Answer:

on moon he can jump 4.2 m high

Explanation:

given data

gravitational acceleration on moon a(m) = 1/6

jump = 0.7 m

to find out

how high could he jump on the moon

solution

we know gravitational acceleration on earth a =  g = 9.8 m/s²

so on moon am =  9.8 * \frac{1}{6}  = 1.633 m/s²

so if he jump on earth his speed will be for height 0.7 m i s

speed v = \sqrt{2gh}

v = \sqrt{2(9.8)0.7}

v = 3.7 m/s

so if he hump on moon

height will be

height = \frac{v^2}{2*a(m)}  

put here value

height =  \frac{3.7^2}{2*1.633)}  

height = 4.2 m

so on moon he can jump 4.2 m high

The force of gravity acting<br> on a child's mass on earth is 490 newtons. what's the child's mass?
UNO [17]
F = m • a

What we know:
- Gravity: 9.8 m/s
- Force: 490 N

Equation derived:
m = F/a
m = 490/9.8
= 50 kg
