a constant net forced of 150 N is exerted to accelerate a cart from rest to velocity of 45 m/s in 8 seconds. what is the mass of the cart?

The mass of the cart is 26.7 kg.

Explanation:

To find this answer use the formula for acceleration first to find how fast the object had to be acccelerating to gain a velocity of 45m/s in 8 seconds flat.

Here's the formula for acceleration:

a = V- V₀ ÷ T (Wher V = final velocity; V₀ = Initial velocity, and T = time)

Plug all known values into the equation and you get -

a = (45m/s - 0m/s) ÷ 8 , which works out to 5.625 m/s²

Once you have this value then you place it into the equation for finding an object's mass, and that formula is:

M =  or M =

This works out to  26.6667 kg or approx. 26.7 kg if you are asked to round it to three significant figures.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
