A box has an applied force of 105 N [Right] and a force of friction of 65 N [left] as it
slides across a level floor. The mass of the box is 7.14 kg.
a) Calculate the force of gravity on the box. [1]
b) Draw and label a free-body diagram with all four forces acting on the box ( I
mentioned three but there is another). [2]

Astring that is fixed at both ends has a length of 1.05 m. when the string vibrates at a frequency of 91.0 hz, a standing wave with five loops is formed. (a) what is the wavelength of the waves that travel on the string? (b) what is the speed of the waves? (c) what is the fundamental frequency of the string?

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.

What is the final velocity of the initial velocity of 25 and -50?
