In the image below, a worker is pushing a crate with a mass of 25 kg up a ramp at a constant rate. Ignoring friction, how much force must the worker apply so that the crate continues to move at the same speed? (Recall that g =
9.8 m/s2)

A. 35.3N
B. 83.8N
C. 50.2N
D. 16.2N


Sagot :

The image is missing, so i have attached it.

Answer:

B. 83.8N

Explanation:

The mass of the worker is 25 kg

From the image, the angle of the ramp is 20°

To find the force that the worker must apply to make the crate continue to move at the same speed, we will use the formula;

F = mg sin θ

F = 25 × 9.8 × sin 20

F ≈ 83.8 N
