Answer:
a = 17.81 m/s²
Step-by-step explanation:
Given that,
Shaun and his friend give Shirley a big shove all at once, applying a force of F=980 N
Let us assume that the mass of Shaun and his friend is 55 kg.
Let a is the acceleration during this shove.
The second law of motion is given by :
F = ma
So, the acceleration of Shirley is 17.81 m/s².
