A child is pushing a shopping cart at a speed of 1.5 m/s. How long will it take this child to push the cart down an aisle with a length of 9.3 m?
d = Vo*t + 0.5at^2,
a = 0,
d = Vo*t + 0.5*0*t^2,
d = Vo*t + 0,
d = Vo*t,
t = d/Vo = 9.3 / 1.5 = 6.2s.
To find the time it will take for the child to push the cart down the aisle, we can use the equation:
Time = Distance / Speed
Given that the speed of the cart is 1.5 m/s and the distance is 9.3 m, we can substitute these values into the equation:
Time = 9.3 m / 1.5 m/s
Calculating the division:
Time = 6.2 s
Therefore, it will take the child approximately 6.2 seconds to push the cart down the aisle.
To find the time it takes for the child to push the cart down the aisle, we can use the equation for speed:
Speed = Distance / Time
Rearranging the equation, we get:
Time = Distance / Speed
In this case, the distance is 9.3 m and the speed is 1.5 m/s. Plugging in these values, we can calculate the time it takes:
Time = 9.3 m / 1.5 m/s
Using division, the answer is approximately 6.2 seconds.
So, it will take the child approximately 6.2 seconds to push the cart down the aisle.
