Answer:
20m/s²
Explanation:
force = mass*acceleration
acceleration = force ÷ mass
acceleration = 200N ÷ 10kg
acceleration = 20m/s²
Given :
Initial velocity , u = 0 m/s .
Acceleration due to gravity on moon ,
.
Height , h = 2 m .
To Find :
Final position after falling for 1.5 seconds .
Solution :
We know , by equation of motion :

Here ,
.
So , equation will transform by :

Therefore , the height form moon's surface is 1.88 m .
Hence , this is the required solution .
Explanation:
You can find the net force by summing the force components:
∑F = 22 N − 1 N
∑F = 21 N
Or by using Newton's second law:
∑F = ma
∑F = (7 kg) (3 m/s²)
∑F = 21 N
Her acceleration is
(250) divided by (the swimmer's mass, in kilograms).
The unit is " meters per second² " .
