Force acting on a body is expressed as 2t2 + 3t N (Newton), where t is the time in seconds. Distance covered by the same body is represented as 2t meters. Calculate the work done at t = 10 seconds?

Answer:
work done =4600joule
Step-by-step explanation:
force =2t^2+3t (Newton)
Distance=2t (meter)
work=force ×distance
work = (2t^2+3t)(2t)
work=2t^2×2t+3t×2t
work=4t^3+6t^2
work done at t=10second
work=4×10^3+6×10^2
work=4×1000+6×100
work=4000+600
work=4600 joule
