The answer would B, trust me it’s right
F = ma, Where F is force is in N, mass is in kg, = 2kg, a is acceleration in m/s²
12 = 2a
2a = 12
a = 12/2
a = 6
Acceleration = 6 m/s²
Answer:

Answer:
Final speed, v = 12.57 m/s
Explanation:
Given that,
Slope with respect to horizontal, 
Distance travelled, d = 19 m
Initial speed of the cyclist, u = 9.5 m/s
We need to find the final speed of the cyclist. Let h is the height of the sloping surface such that,

h = 3.46 m
Let v is the final speed of the cyclist. It can be calculated using work energy theorem as :



v = 12.57 m/s
So, the final speed of the 12.57 m/s. Hence, this is the required solution.
