Gayle runs at a speed of 4.00 m/s and dives on a sled, initially
atrest on the top of a frictionless, snow-covered hill. aftershe
has descended a vertical distance of 5.00m, her brother, who
isinitially at rest, hops on her back, and they continue down
thehill together.
gayle's mass is 50.0kg, the sled's mass is 5.00kg and her
brotherhas a mass of 30.0kg.

what is their speed at the bottom of the hill if the total
verticaldrop is 15.0m?

What is tan(61)? а. 1.80 b. 0.49 c. 0.61 d. 0.87

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.

Select all of the following that are equal to an impulse of 20 unitsa) force= 5, time= 5.5b) force= 25, time= 0.8c) force= 0.1, time= 200d) force= 10, time= 2(its b, c, and d)(also in order to find answer they have to add to get the unit)ex= 25x.8=20 or .1x200=20
