Answer:
76 seconds
Explanation:
Using the formula t=vf-vo/a, where t=time, vf= final velocity, v0= initial velocity, and a= acceleration, we can solve for your problem.
Plug in known variables...
t=200-10/a
we can solve for a by using the formula F=ma where f=force, m= mass, and a=acceleration and rearranging it to solve for a.
a=F/m
Plug in known variables...
a=250N/100kg
a=2.5m/s^2
Plug in our newly found acceleration of 2.5 m/s^2 into our first equation and solve....
t=190/2.5
t=76 seconds

Sound waves travel around the boxed room causing them to bounce off the nearest walls to the end of the room
Answer:
D
Explanation:
Now the net force is the applied force minus the frictional force; this is expressed mathematically as:
Fnet= Fappplied - Ffrictional
Now the frictional force is given as ;
Coefficient of friction × normal reaction
Normal reaction is the weight of the human acting in opposite direction.
Normal reaction of the human is ;
35 × 9.8 = 343N { note that weight = m× g and g= 9.8m/S2, a known standard }
Hence the Frictional force =343×0.4 =137.20N
Hence Fnet = 200-137.20 = 62.8N
Fnet = 63N to the nearest whole
