Can someone me because i don’t really understand thxxx

One

Without any consideration other than the givens the acceleration will be 2 m/s^2

Givens

F = 100 N

m = 50 kg

a = ?

Formula

F = m*a

Solution

100 N = 50 kg * a                          Divide both sides by 50

100 N/50 kg = 50 kg * a / 50 kg

2 m/s^2 = a

Two

The (downward) gravitational force is

Givens

F = m * a

m = 50 kg

a = 9.8 m/s^2

Solution

F = 50 * 9.8

F = 490 N

B
