Answer:

The "average speed" of the rider is <u>40 km/h</u>.

Explanation:

The average speed of a rider finishes by bicycle is the total distance traveled by bicycle divided by the time to cover that distance.

\text { Average speed }=\frac{\text { total distance }}{\text { total time }}

\Delta \mathrm{s}=\frac{\Delta \mathrm{d}}{\Delta \mathrm{t}}

∆s =Average speed

∆d = total distance

∆t = total time

Total distance of the rider finishes by bicycle = 120 km

Total time of the rider's bicycle = 3 hours

\text { Average speed }=\frac{120}{3}

Average speed = 40 km/h

The "average speed" of the rider is <u>40 km/h</u> .

A particle whose speed is 50 m/s moves along the line from A(2,1) to B(9,25). Find its velocity vector in the form of ai +bj.
Kitty [74]

To write it in the form ai + bj, we need to find a and b which are:

a = x component

b = y component

 

length of x = 9 – 2 = 7

length of y = 25 – 1 = 24

 

tan θ = 24 / 7

θ = 73.74°

 

a = (50 m/s) cos 73.74

a = 14 m/s

 

b = (50 m/s) sin 73.74

b = 48 m/s

 

Hence,

14i + 48j

A boy starting from rest, slides down a snowy hill on a sled. He travels 174.19 m to the bottom of the hill. He accelerates
AfilCa [17]

Answer:

11.6 s

Explanation:

We can use equation of motiom to solve this

s = ut +  \frac{1}{2} a {t}^{2 }  \\ 174.19 = (0)t +  \frac{1}{2} (2.61){t}^{2 }  \\ t = 11.6s
