Question

A car is being driven by a force of 2.5 ×10^10 N.Travelling at a constant speed of 5 m/s ,it takes 2 minutes to reach a certain place . Calculate the work done....

Please give correct answer

Answer 1

Work done = Force * Displacement or (sometimes distance traveled )

Given, Force = 2.5*10^10,

Speed = 5m/s,
Time = 2min = 120 sec,

Distance traveled = 5*120 = 600m,

Now work done = 2.5*10^10 * 600,

=>1500*10^10,

Hope you understand !

Answer 2

Hey there!

Given,
Speed, v = 5 m/s
Force,
$F = 2.5 \times {10}^{10}$

Time, t = 2min = 120 sec

Distance covered, d= 5 m/s × 120s
= 600m

Workdone = Force × Distance

W = F × d

$= 2.5 \times {10}^{10} \times 600$
$= 1500 \times {10}^{10}$
$= 15 \times {10}^{12}$

Hence,
Workdone = 15 × 10¹² Joules
