Length of the slope is given as
also the inclination is given as
now the horizontal displacement is let say "x"
now from geometry we can say
now substitute all values in it
<em>so it will displace horizontally by 12.99 m</em>
Answer:
<u>1000N</u>
Explanation:
It takes 200N to expand 15cm of one string.
For 5 strings, force required =
200 x 5 = <u>1000N</u>
Answer:
166 kg *m/s
44 N upward
39 m/s east
Explanation:
The short answer: If it has direction, it's a vector.
The long answer:
Vectors, unlike scalars, have direction. The first one, 166 kg*m/s is momentum, since momentum is velocity*mass, and velocity is a vector, momentum must be a vector.
44 Newtons is a vector since it has direction, in this case, upward. Force is acceleration*mass, and since acceleration is a vector, force must be a vector.
39 m/s is velocity, velocity has a direction, therefore it's a vector.
13.7 grams is mass since mass doesn't change with direction, it's a scalar, the opposite of a vector.
86 miles per hour has speed, but speed has no direction, therefore it's a scalar.
12 meters is distance, distance has no direction, therefore it's a scalar.
