Find the acceleration of a 2500 kg truck that has a force acted on by its wheels of 7kN. A force of friction of 1500 N is also acting on the truck.

Expert Solution

Answer : Given problem , mass of the truck (m) = 2500 kg

force acting on the wheels (f1) = 7 kN = 7000 N

This force say acting on forward direction.

frictional force acting on the truck (f2) =1500 N

This frictional force oppose the wheels force.So the resultant force F = f1 - f2

F = 7000 -1500 = 5500 N

We know that force F = ma

Where a is acceleration, a = F/m

a = 5500/2500 = 2.2 m/s^2

Therefore acceleration of the truck , a = 2.2 m/s^2

A certain object has a mass m $ 100 kg and is acted on by a force

A certain object has a mass m $ 100 kg and is acted on by a force f (t) = 500[2 – e-t sin(5πt)] N. The mass is at rest at t = 0. Use MuPAD to compute the object’s velocity at t = 5 s. The equation of motion is mυ̇ = f(t).

The figure gives the acceleration of a 4.0 kg particle as an applied force moves it from rest along an x axis from x = 0 to x = 9.0 m. The scale of the figure's vertical axis is set by as = 8.0 m/s2. How much work has the force done on the particle when the particle reaches (a) x = 4.0 m, (b) x = 7.0 m, and (c) x = 9.0 m? What is the particle's speed...

Force, speed , acceleration and momentum

Sometimes it is convenient to construct a system of units so that all quantities can be expressed in terms of only one physical quantity. In one such system, dimensions of different quantities are given in terms of a quantity X as follows:[position] = [𝑋𝛼]; [speed] = [𝑋𝛽]; [acceleration] =[𝑋𝑝]; [linear momentum] = [𝑋𝑞]; [force] = [𝑋𝑟]. Then

Find the useful power output (in W) of an elevator motor that lifts a 2500 kg load a height of 30.0 m in 12.0 s, if it also increases the speed from rest to 4.00 m/s. Note that the total mass of the counterbalanced system is 10,000 kg—so that only 2500 kg is raised in height, but the full 10,000 kg is accelerated. watts What does it cost (in cents), if electricity is $0.0900 per kW · h? cents
