Question

If the horse and rider have a combined mass of 572 kg, what force would be required to accelerate them 5 kph per second? Assume there is no friction. a. 50 N b. 100 N c. 250 N d. 500 N

Answer 1

To calculate the force required to accelerate the horse and rider, you can use Newton's second law of motion. The force is approximately 796 N.

Step-by-step explanation:

To calculate the force required to accelerate the horse and rider, we can use Newton's second law of motion, which states that force equals mass times acceleration (F = m * a). In this case, the mass is 572 kg and the acceleration is 5 kph per second. First, we need to convert the acceleration from kph per second to meters per second. Since 1 kph is equal to 0.2778 m/s, the acceleration would be 5 * 0.2778 = 1.389 m/s².

Now, we can plug in the values in the formula. F = 572 kg * 1.389 m/s² = 795.708 N. Therefore, the force required to accelerate the horse and rider is approximately 796 N.
