Answer:

500\:\mathrm{m}\\60\:\mathrm{s}\\8.\bar{3}\:\mathrm{m/s}}

Explanation:

The total distance travelled is shown on the graph to be \fbox{$500\:\mathrm{m}$}.

The total is shown on the graph to be \fbox{$60\:\mathrm{s}$}.

Average speed is given by S=\frac{d}{t}, where d is the total distance travelled and t is time.

Therefore, the average speed is:

S=\frac{500}{60}=\fbox{$8.\bar{3}$\:\mathrm{m/s}}.

Explanation:

d =  \frac{1}{2} a {t}^{2}  + vt \\ d = 75 \\ t = 5 \\ v = 0 \\  \\ 75 =  \frac{1}{2}  \times 25a + 0 \\ a = 6 \frac{m}{ {s}^{2} }  \\

A simple pendulum 2 m long swings through a maximum angle of 30 ? with the vertical.
Alexus [3.1K]
The complete question was calculate the period T assuming the smallest amplitude.
Using the equation;
T = 2 π√(L/g)
Where T is the period in seconds, L is the length of the rod or wire in meters and g is the acceleration due to gravity. 
Hence; T = 2×3.14 × √(2/9.81)
                = 6.28 × 0.4515
                = 2.836 seconds

A rock is dropped from the top of a tower. When it is 40 meters above the ground velocity of 17 m/s. When its velocity is 24 m/s
eimsori [14]

Answer:

Option B is the correct answer.

Explanation:

Let us consider 40 meter above ground as origin.

Initial velocity = 17 m/s

Final velocity = 24 m/s

Acceleration = 9.81 m/s

We have equation of motion v² = u² + 2as

Substituting

         24² = 17² + 2 x 9.81 x s

           s = 14.63 m

Distance traveled by rock = 14.63 m down.

Height of rock from ground = 40 - 14.63 = 25.37 m = 25.4 m

Option B is the correct answer.
