Question

The goliath beetle, can reach a mass of 0.080 kg. Suppose a goliath beetle is placed on a slope that makes an angle of 37.0 degrees with the horizontal. Find the acceleration of the beetle along the slope, assuming the slope is frictionless.

If a force of 1.40 N upward along the slope is applied to the beetle in the problem above, what is the beetle's acceleration?

Answer 1

Use F = ma for the acceleration. In this case, F is component of the weight down the slope. The mass will cancel out.

For part 2 , use F = ma again, but the net force in this case is 1.40 N MINUS the weight component down the slope

Answer 2

for first part F=gravitysin[37] which is 5.9m/s^2
