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

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

the answer is 12 as i may remember
