Acart is pulled by a force of 250 n at an angle of 35 degrees above the horizontal the cart accelerates at 1.4 m/s^2 what is the mass of the cart

146 kg

Explanation: We need to start with finding the force because the given force is not including the friction caused by the angle. So first, we need to find the adjusted force after taking into account the friction.

Step 1: So, since it is being pulled to the right, we know this since it is positive, we need to find the angle and we use the sinФ function like this:

(Force)(sin(angle)) = (250N) (sin(35)) = 204.78N

Step 2: Now you are ready to find the mass. The formula is:

mass = force/acceleration

Mass = 204.78/1.4 = 146.42

Step 3: Round the answer to the nearest whole number.

Mass = 146

(75°f − 32) × 5/9 = 23.889°c

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
