Explanation Given Info: A tabulated integral is given as ∫ 0 ∞ x n e − α x d x = n ! α n + 1 where n is a positive integer and α is a positive constant. The expression for f ( v ) is, f ( v ) = 4 π ( m 2 π k T ) 3 2 v 2 e − m v 2 2 k T f ( v ) is the probability per unit speed interval(distribution function). m is mass v is molecular speed. k is Boltzmann constant. T is absolute temperature. Substitute 4 π ( m 2 π k T ) 3 2 v 2 e − m v 2 2 k T for f ( v ) in ∫ 0 ∞ v f ( v ) d v . ∫ 0 ∞ v f ( v ) d v = ∫ 0 ∞ v [ 4 π ( m 2 π k T ) 3 2 v 2 e − m v 2 2 k T ] d v = ∫ 0 ∞ 4 π ( m 2 π k T ) 3 2 v 3 e − m v 2 2 k T d v = 4 π ( m 2 π k T ) 3 2 ∫ 0 ∞ v 3 e − m v 2 2 k T d v Thus, ∫ 0 ∞ v f ( v ) d v = 4 π ( m 2 π k T ) 3 2 ∫ 0 ∞ v 3 e − m v 2 2 k T d v (I) Substitute v 2 for x

A block of mass m₁ = 10.0 kg is connected to a block of mass m₂ = 34.0 kg by a massless string that passes over a light, frictionless pulley. The 34.0-kg block is connected to a spring that has negligible mass and a force constant of k = 200 N/m as shown in the figure below. The spring is unstretched when the system is as shown in the figure, and the incline is frictionless. The 10.0-kg block is pulled a distance h = 22.0 cm down the incline of angle 0 = 40.0° and released from rest. Find the speed of each block when the spring is again unstretched. m/s Vm1 Vm2 m/s mi m2 k i

Truck suspensions often have "helper springs" that engage at high loads. One such arrangement is a leaf spring with a helper coil spring mounted on the axle, as in the figure below. The helper spring engages when the main leaf spring is compressed by distance yo, and then helps to support any additional load. Consider a leaf spring constant of 5.45 × 105 N/m, helper spring constant of 3.60 × 105 N/m, and y = 0.500 m. Truck body Dyo Axle (a) What is the compression of the leaf spring for a load of 4.90 × 105 N? m (b) How much work is done compressing the springs? ]

A skier of mass 75 kg is pulled up a slope by a motor-driven cable. (a) How much work is required to pull him 50 m up a 30° slope (assumed frictionless) at a constant speed of 2.8 m/s? KJ (b) What power (expressed in hp) must a motor have to perform this task? hp
