What force is needed to accelerate a child on a sled (total mass = 60 kg) at 1.25 m/s2?
mass times acceleration. Your units are correct and your answer will be in Newtons of force. However m/s^2 not m/s2. The convention online is to write exponents as ^
To determine the force needed to accelerate the child on a sled, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a).
The mass of the child and the sled combined is 60 kg, and the acceleration is 1.25 m/s^2. Plugging these values into the equation, we can calculate the force (F):
F = m * a
F = 60 kg * 1.25 m/s^2
F = 75 N
Therefore, the force needed to accelerate the child on a sled at 1.25 m/s^2 is 75 Newtons.
To determine the force needed to accelerate a child on a sled, we 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.
In this case, the mass of the child and the sled is given as 60 kg, and the acceleration is given as 1.25 m/s^2.
According to Newton's second law, the force (F) can be calculated by the formula:
F = m * a
where:
F is the force,
m is the mass,
a is the acceleration.
Plugging in the given values:
F = 60 kg * 1.25 m/s^2
Now we can calculate the force:
F = 75 N
Therefore, a force of 75 Newtons (N) is needed to accelerate the child on the sled at a rate of 1.25 m/s^2.
