What force is needed to accelerate a child on a sled (total mass = 65.0 kg) at 1.75 m/s^2
113.75
To find the force needed to accelerate the child on a sled, you can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.
The formula for this is:
Force = Mass * Acceleration
In this case, the mass of the child and the sled is given as 65.0 kg, and the acceleration is given as 1.75 m/s^2.
Plugging these values into the equation, we get:
Force = 65.0 kg * 1.75 m/s^2
Calculating this gives us:
Force = 113.75 kg·m/s^2
Therefore, the force needed to accelerate the child on a sled is 113.75 N (Newtons).
