A 25 kg suitcase is being pulled with constant speed by a handle that is at an angle of 26 ∘ above the horizontal. If the normal force exerted on the suitcase is 170 N , what is the force F applied to the handle?

Expert Solution

Given that mass m = 25 kg , Normal Force N = 170 N

From Normal Forces F sin θ +N = W

F sin θ + N = m g

F sin 26 ⁰ + 170 N = 25 kg * 9.8m/s²

Fsin 26 ⁰ + 170 N = 245 N

Fsin 26 ⁰ = 245 N - 170 N

= 75 N

F = 75 N / sin 26

= 75 / 0.438

=171.08 N

A man on a bike of total mass 100 kg, is free-wheeling at a constant speed of 15 ms-1 down a hill with a gradient of 10%. He wants to slow down to a safer speed, so he applies the brake lightly to produce a constant braking force of 84 N. The air resistance is proportional to the square of the speed. (a) Calculate the deceleration when his speed has dropped to 12 ms-1. (b) At what speed will his...
