Aclerk can lift cylindrical packages 1 meter vertically, or can roll them up a 2-meter-long ramp to the same elevation. with the ramp, the applied force required is abouta. twice as much. b. half as muchc. four times as muchd. the same

Explanation:

For lifting the object vertically , force to be applied is equal to its weight

So in the first case applied force = mg

In the second case , Only a  component of mg acts along the ramp which is equal to mg sinθ where θ is inclination of ramp with horizontal

Here sinθ = 1/2

So force required = mg sinθ

= mg x 1/2

1/2 mg

So option  B is correct.

the right answer is 0.3 meters per second
