The acceleration is 
Explanation:
We can answer this question by using Newton's second law, which states that the net force acting on an object is equal to the product between the mass of the object and its acceleration:
where
F is the force
m is the mass
a is the acceleration
In this problem, we have
m = 25 kg is the mass of the rider+bicycle
F = 400 N is the force
Solving for a, we find the acceleration:

Explanation:
The gravitational potential energy of the ball (relative to the ground) is given by
where
m = 2 kg is the mass of the ball
g = 9.8 m/s^2 is the acceleration due to gravity
h = 4 m is the height of the ball above the ground
Substituting numbers into the formula, we find
I believe the answer is a
