Solution:According to question: Acceleration (a) `= 5m//s^2` and Mass (m) = 1000 kg, therefore, Force (F) =? We know that, `F = m xx a` `= 1000 kg xx 5m//s^2` temperature on saturn dayWebAns: 18 km/h = 18km/1h = 18000m/3600s = 5 m/s. 2 km/min = 2km/1min = 2000m/60s = 33.3 m/s. Thus the average speeds of the bicycle, the athlete and the car are 5 m/s, 7 m/s and 33.3 m/s respectively. So the car is the fastest and the bicycle is the slowest.
