a girl pulling a sled with a mass of 6.0 kg to the left with a force of 10.0 N at a 30.0 degree angle. There is a 1.5 N force of
Aleonysh [2.5K]

For the girl pulling a sled with a mass of 6.0 kg t the left with a force of 10.0 N at a 30.0° angle, we have:

a) The normal force acting on the sled is 294 N.

b) The acceleration of the sled is 1.2 m/s².

a) We can calculate the normal force acting on the sled, with the sum of all the forces acting in the vertical direction:

(1)

Where:

W: is the weight force or force of gravity = 58.8 N

: is the component of the applied force in the y-direction

N: is the normal force =?

The vertical component of the force () can be calculated as follows:

(2)

Where:

F: is the applied force = 10.0 N

θ: is the angle (with the horizontal) = 30.0°

By entering equation (2) into (1) we have:

Hence, the normal force acting on the sled is 294 N.

b) The acceleration of the sled can be found with the forces acting on the x-direction:

Where:

a: is the acceleration =?

m: is the mass = 6.0 kg

: is the component of the applied force in the x-direction = Fcos(θ)

: is the force of friction = 1.5 N (it is negative because is in the opposite direction of motion)

Therefore, the acceleration is:
