Oct 13, 2021 · (1) A force of 100 newtons accelerates a mass of 5 kg for 10 seconds. If the mass is initially at rest, calculate the final velocity. Firstly it is necessary to calculate the acceleration. F = 100 newtons. m = 5 kg. F = ma so a = F/m = 100/5 = 20 m/s 2. Next work out the final velocity, knowing the acceleration: Substitute for u, a and t

Ans. W = F × d = 25 N × 20.0 m = 50 J 2. A force of 120 N is applied to the front of a sled at an angle of 28.0 above the horizontal so Ans. W = F• d cos = 120 N • 500 m • cos 35.0 = 49,149.12 N 4. A rubber stopper, which has a mass of 38.0 grams, is being swung in a horizontal circle which A mass m = 3.00 kg is added to the end

4.22 A bulldozer pushes 500 kg of dirt 100 m with a force of 1500 N. It then lifts the dirt 3 m up to put it in a dump truck. How much work did it do in each situation? Solution: W = ∫ F dx = F ∆x = 1500 N × 100 m = 150 000 J = 150 kJ W = ∫ F dz = ∫ mg dz = mg ∆Z = 500 kg × 9.807 m/s2 × 3 m = 14 710 J = 14.7 kJ

Calculate the force exerted on the wall assuming that force is horizontal while using the data in the schematic representation of the situation. Note that the force exerted on the wall is equal in magnitude and opposite in direction to the force exerted on the horse, keeping it in equilibrium. The total mass of the horse and rider is 500 kg.

And thus we're starting out 3 50 plus force 4650. And then we're changing at a constant rate of ah 100. The book it's leaking out at a constant rate. 100 t we could censored in with Ah, change in or similar to a slope. You could have that 100 t rearranging. Rearranging this.
