1. Four forces act on a hot-air balloon, shown from the side in the figure below. Find the magnitude and direction of the resultant force on the balloon if F1 = 4900 N, F2 = 1400 N, F3 = 950 N, and F4 = 4050 N.
2. An 1900 kg car is moving to the right at a constant speed of 2.40 m/s.
(a) What is the net force on the car?
? N to the right
(b) What would be the net force on the car if it were moving to the left?
? N to the left
3. Determine the normal force for a laundry basket with a mass of 5.2 kg in each of the following situations
(a) at rest on a horizontal surface
(b) at rest on a ramp inclined at 12° above the horizontal
(c) at rest on a ramp inclined at 25° above the horizontal
(d) at rest on a ramp inclined at 45° above the horizontal
4. A 3.7 kg bag of groceries is in equilibrium on an incline of angle ? = 25°. Find the magnitude of the normal force on the bag.
please, anyone know how to do this, and i want the work too!!!!!!!!!!
