Achild pulls on a wagon with a horizontal force of 75 n. if the wagon moves horizontally a total of 42 m in 1.5.0 min, what is the average power generated by the child? a) 53 w b) 35 w c) 46 w d) 43 w

B) 35 W

Explanation:

Force applied by child =  75 N = F

Distance travelled by child = 42 m = d

Time traveled for is 1.5 min = 1.5×60 = 90 seconds = t

Work done by the child

W = Fdcosθ

⇒W = 75×42cos0

⇒W = 3150 Joule

Power is defined as work done per unit time

∴ The average power generated by the child is 35 W

the answer would be 32*f
