Answer :
The minimum horsepower must a motor have to be able to drag 310 kg box along a level floor at a speed of 1.20 m/s is 2.199 horse power.
What is called friction?
The resistance to motion of one object travelling in relation to another is referred to as friction. It is not regarded as a fundamental force like gravity or electromagnetic, according to the International Journal of Parallel, Emergent and Distributed Systems(opens in new tab).
First change the mass of 310kg by multiplying by 9.8(gravity), to get 3038 N which equals 'n'
f=μn = (.45)(3038)
= 1367.1N
Use work formula W= fΔx
= (1367.1N)(1.2m/s) = 1640.52 Joules/sec
(1 Watt = 1 Joules / sec) so you get 1640.52 watts
1 horsepower = 746 watts
1640.52 watt/ 746 watt
= 2.199 horse power
Therefore, the minimum horsepower must a motor have to be able to drag 310 kg box along a level floor at a speed of 1.20 m/s is 2.199 horse power.
