Answer:
Isaac Newton discovered that as an object's mass increases, the gravitational attraction of that object increases. Thus, the gravitational attraction on the Moon is much less than it is here on Earth, and a person weighs less on the Moon.
hope this helps!

OKAy okay here Please laugh kinda cringe but...
Explanation:
Two hunters are out in the woods when one of them collapses. He’s not breathing and his eyes are glazed. The other guy whips out his cell phone and calls 911.
“I think my friend is dead!” he yells. “What can I do?”
The operator says, “Calm down. First, let’s make sure he’s dead.”
There’s a silence, then a shot. Back on the phone, the guy says, “OK, now what?”
Answer:
29.6 m
Explanation:
Work is change in KE, and at the bottom of the hill, the car only has KE. Therefore, the car's total mechanical energy (ME) at the bottom of the hill must be equal to its KE (450 000 J). At the top of the hill, the car is no longer moving, so its total energy must be all gravitational potential energy. Following convervation of ME:
Answer:
R = mg
F = µsR
Fs= 0.4 × ( 88 × 10)
Fs = 772 N
Fk= µk R
Fs= 1.33 × 880 N
Net force = (772+(1.33×880))-240 N
