What force is needed to accelerate a child on a sled with the total mass of 43kg at 1.5m/s
To calculate the force needed to accelerate an object, we can use Newton's second law of motion, which states that the force acting on an object is equal to its mass multiplied by its acceleration:
Force = Mass × Acceleration
In this case, the mass of the child on the sled is 43 kg, and the acceleration is given as 1.5 m/s². Plugging these values into the equation, we can calculate the force:
Force = 43 kg × 1.5 m/s²
Force = 64.5 N
Therefore, the force needed to accelerate the child on the sled is 64.5 Newtons.
