Sagot :

1. It's because seatbelts reduce serious crash-related injuries and death. If the passenger and the driver were wearing a seat belt, the seat belt would act as the unbalanced force, it would stop you from being in motion. Seat belts will hold the driver and passenger down, protecting them from their own inertia.

2. G = mass- 4.0kg

acceleration- 2.0 m/s²

R = The amount of force applied to it

E = F = ma or (m) (a)

S=

F = ma

F = (4.0kg) (2.0 m/s²)

F = 8 N

A=. F (force)= 8 N amount of force applied to it

3. G = mass- 50.0 kg

force- 20.0 Newton applied to it

R = acceleration=? (or you can write) the resulting acceleration of the object

E= F

------

m

S= F

a = -----

m

20.0 N

a = -------------

50.0 kg

A=. a(acceleration) = 4 m/s² , is the resulting acceleration of the object
