To calculate the speed, we need to use the formula: Speed = Distance / Time.
Given that the man walks 20km in 6 minutes, we can calculate his speed as follows:
Speed = 20km / 6 mins
Speed = 3.33 km/min
So, his speed is approximately 3.33 km/min.
Acceleration is the rate at which the speed of an object changes over time. In this case, since they only provide the distance and time, we cannot calculate the acceleration.
Momentum is calculated using the formula: Momentum = Mass x Velocity.
To calculate momentum, we need to convert the man's weight from pounds to kilograms first:
Weight = 150 lbs
Weight in kg = 150 lbs / 2.205 lbs/kg (conversion factor)
Weight in kg = 68.04 kg (rounded to the nearest hundredth)
Since the initial velocity is given as 0 km/min, the momentum can be calculated as follows:
Momentum = Mass x Velocity
Momentum = 68.04 kg x 0 km/min
Momentum = 0 kg·km/min
Therefore, the momentum is 0 kg·km/min.
A man is in a walk race. He walks 20km in 6 mins. What is the speed, acceleration and momentum. He weighs 150lbs. He started at 0.
