A 5kg wooden box is pulled along the floor at a constant speed, with a force of 70N at an angle of 25° to the horizontal. -) calcuate the magnitude of the support force from the floor and the...

the 2 kg block in the figure slides down a frictionless curved ramp, starting from rest at a height of h=2.0 m the block the slides d= 8.0 m on a rough horizontal surface before coming to rest. what...

If a circuit with a 9 Ohms of resistance is powered by a 1.5 Volt battery, what would happen to the voltage drop across the resistor if a second 1.5 Volt battery was connected in series with...

The legs of a tripod make equal angles of 90° with each other at the apex, where they join together. A 111-kg block hangs from the apex. What is the compressional force in each of the three legs?...

SSF=ratio of track/(2•height of center of gravity). Do I just start taking guesses and use ac=v2/R. Then use a=g•SSF, to get a comparative answer? For example: 50mph--- ac=502/50=50. SSF=50/32...

of a centrifuge in which a particle 10.0 cm from the axis of rotation experiences a radical acceleration of 1.00 x 10^3 times gravitational acceleration g.

A car starting from rest accelerates to the left. It takes 14 seconds to travel a distance of 20 meters. What is the car's average velocity? I'm really confused by this question I'm not sure...

A block of mass m1=0.700 kg is connected over a pulley to a mass m2. For an angle of theta=30.0° and a coefficient of kinetic friction of μ= 0.400, an acceleration of magnitude a=0.450 m/s² is...
