note ... find acceleration by using distance and time (ignore ”incline” ... just treat it like linear motion of object starting from rest). A 1.8 kg mass starts from rest and slides down an inclined plane 8.8×10−1 m long in 0.54 s. What net force is acting on the mass ...

A 2kg mass is released from rest and slides down an inclined plane of 60 degrees a distance of 1 eter. It strikes a 250 N/m spring. What is the maximum compression of a spring?

A child slides down a slide with a 28° incline, and at the bottom her speed is precisely three-fifths what it would have been if the slide had been frictionless. Calculate the coefficient of kinetic friction between the slide and the child Height= length/sin28 energy available...

physics
A 20 kg block slides with an initial speed of 11 m/s up a ramp inclined at an angle of 25o with the horizontal. The coefficient of kinetic friction between the block and the ramp is 0.8. Use energy conservation to find the distance along the incline that the block slides ...
