A205 kg log is pulled up a ramp by means of a rope that
isparallel to the surface of the ramp. the ramp is inclined at30%
with respect to the horizontal. the coeffecient ofkinetic frictin
between the log and the ramp is 0.900 and the loghas an
acceleration of 0.800 m/s2. find the tension in therope.

2.737 kN

Explanation:

Given

mass of log(m)=205 kg

ramp inclination

coefficient of kinetic friction between log and ramp is ()=0.9

log has an acceleration of 0.8 m/s^2

Let T be the tension in the rope

Where =Sin component of weight

(Where N is Normal reaction)

sin30=0.5

cos30=0.866

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.
