A catcher “gives” with the ball when he catches a 0.179 kg baseball moving at 16.5 m/s. If he moves his glove a distance of 2.25 cm, what is the average force acting on his hand? Answer in units of kN.

A 19.5 kg block is dragged over a rough, horizontal surface by a constant force of 110 N acting at an angle of angle 31.1◦ above the horizontal. The block is displaced 6.74 m,and the coefficient of kinetic friction is 0.156. What is the net work done on t...

If 5.00 mL of HCl require 4.59 mL of 0.9581 M NaOH to just consume the HCl, what is the concentration of the HCl?

An Atwood machine is constructed using a disk of mass 2 kg and radius 20.1 cm. 2.3 m= distance between weights 1.53 kg= weight 1 1.18 kg=weight 2 What is the acceleration of the system? The acceleration of gravity is 9.8 m/s2 . Answer in units of m/s2.

A 16 kg mass is attached to a cord that is wrapped around a wheel with a radius of 10.9cm. The acceleration of the mass down the frictionless incline is measured to be 1.4 m/s2.The angle of incline is 36 degrees. Assume the axle of the wheel to be frictio...

A horizontal 873 N merry-go-round of radius 1.11 m is started from rest by a constant horizontal force of 70.6 N applied tangentially to the merry-go-round. Find the kinetic energy of the merry-go-round after 3.59 s. The acceleration of gravity is 9.8 m/s...

I did it the way you said and it said it was wrong.

.9581*4.59=X then X/5 = .8795 which is the concentration

is 721.12 ... use KE=(((F*t)^2)g)/W W= 873, F=70.6 t=3.59, g=9.8

nope. THAT'S WHY I CAME HERE!!!
