A 253 kg log is pulled up a ramp by means of a rope that is parallel to the surface of the ramp. The ramp is inclined at 30.0° with respect to the horizontal. The coefficient of kinetic friction between the log and the ramp is 0.820, and the log has an acceleration of 0.700 m/s2. Find the tension in the rope.
On a very muddy football field, a 100 linebacker tackles a 75 halfback. Immediately before the collision, the linebacker is slipping with a velocity of 8.9 north's and the halfback is sliding with a velocity of 7.9 east's.
How much is the spring compacted
A force of 323N is applied horizontally to a crate in order to displace crate 30m across a level floor at a constant velocity. As a result of this work.
A stone is thrown horizontally from the roof of a tall building with a speed of 23.3 m/s. If the cliff is 26.5 high and stone lands on level parking lot below, how far from the building will the stone land?
It shouldn't matter how many calories were consumed or how long the person walked or ran, we are just making a comparison of burning calories while exercising at 5km/h and 15km/h.
Assume that when you ride on your 7.60-kg bike the weight of you and the bike is supported equally by the two tires. If the gauge pressure in the tires is 78.5 lb/in2 and the area of contact between each tire and the road is 7.13 cm2, what is your we..
The coefficient of kinetic friction between the rock and the surface is 0.300. Illustrate what average thermal power is produced as the rock stops?
An air parcel moves northwards and becomes entrained in a strong westerly flow, circling the entire globe in the space of a few weeks. State the name given to this high-level flow and define briefly how its structure is related to lateral and vert..
