Question

acceleration of 1,4.
7.
A 500 kg horse pulls a cart of mass 1500 kg along a level road with an
coefficient of sliding friction is 0.2, then force exerted by earth on horse is​

Answer 1

Answer:

Given that,

Mass of horse = 500 kg

Mass of cart = 1500 kg

Acceleration = 1 m/s2

Friction coefficient = 0.2

Now, the force by the horse

Net force in forward direction = Accelerating force + friction

F=ma+μmg

Now, put the value

 F=m(a+μg)

F=(1500)(1+0.2×10)

F=1500×3

 F=4500N

Hence, the force exerted by the horse in forwarding direction is 4500 N.
