1. mr. ure has a mass of 65 kg, due to the fact that he is way too skinny! what is the force of earth's gravity on him? 2. the force of earth's gravity on a car is 3,050 newtons. what is the car's mass in kg? 3. mr. rees has a mass of 90 kg. how much is the force of earth's gravity on him?

1.

m = mass of Mr. Ure = 65 kg

g = acceleration due to gravity = 9.8 m/s²

force of earth's gravity on Mr. Ure is given as

F = mg

F = 65 x 9.8

F = 637 N

2.

F = force of gravity on car = 3050 N

m = mass of the car = ?

g = acceleration due to gravity = 9.8 m/s²

force of gravity on car is given as

F = mg

3050 = m (9.8)

m = 3050/9.8

m = 311.22 kg

3.

m = mass of Mr. Rees = 90 kg

g = acceleration due to gravity = 9.8 m/s²

force of earth's gravity on Mr. Rees is given as

F = mg

F = 90 x 9.8

F = 882 N
