Child slide down a hill with an acceleration of 2.9 m/s^2 if she start with an initial velocity of 2.3 how far does she travel in 5.0 second

 Distance traveled in 5 seconds = 47.75 meter.

Explanation:

 We have equation of motion , , s is the displacement, u is the initial velocity, a is the acceleration and t is the time.

 In this the velocity of body = 2.3 m/s, acceleration = 2.9 , we need to calculate displacement when t = 5 seconds.

So, distance traveled in 5 seconds = 47.75 meter.

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000
