Answer:
5m/s²
Explanation:
The force exerted on an object is calculated using the formula ;
F = ma
Note that the upward force (F) is 148N
Where;
F = force (N)
m = mass (kg)
a = acceleration (m/s²)
The downward force towards gravity is F' = mg
F' = 10 × 9.8m/s²
F' = 98N
Net force (F - F') = m × a
148 - 98 = 10 × a
50 = 10a
a = 50/10
a = 5m/s²
