PLEASE HELP - basic SUVAT stuff
Goryan [66]

Answer:

1. 5 m/s

2. 8 m/s

3. 10 s

4. 3 m/s

Explanation:

1. Average speed = distance / time

s = 20 m / 4 s

s = 5 m/s

2. First, find the time to travel from A to B:

60 m = 10 m/s × t

t = 6 s

Now find the average speed from A to C:

s = 80 m / (6 s + 4 s)

s = 8 m/s

3. If t is the time traveling from C back to B, and the average speed of the whole trip is 5 m/s, then:

5 m/s = 100 m / (6 s + 4 s + t)

t = 10 s

4. Average velocity = displacement / time

v = 60 m / 20 s

v = 3 m/s

A car started from a rest and accelerated at 9.54 m/s2 for 6.5 seconds. How much distance was covered by the car?
ElenaW [278]

Explanation:

S =ut + 1/2at^2

S = 0×6.5 + (1/2 × 9.54) × 6.5^2

S =0 + 4.77 ×42.25

S=201.5m

16. PHYSICS The height h of a falling object is given by h = vt - gt2, where vis the initial velocity of the object, t is time,
disa [49]

The value of v; initial velocity is determined as, v = h/t + gt.

<h3>What is initial velocity of an object?</h3>

The initial velocity of an object is the velocity of the object before the effect of acceleration, which causes the change of velocity.

h = vt - gt²

to solve for v (the initial velocity) we will make v the subject of the formula.

h + gt² = vt

divide both sides of the equation by t

h/t + gt  = v

Thus, the value of v; initial velocity is determined as, v = h/t + gt.

The average energy per unit time per unit area that reaches the upper atmosphere of the Earth from the Sun, called the solar con
Lynna [10]

Answer: 5.34 MJ

Explanation: The window is a rectangle with area:

A = 1.1(1.5)

A = 1.65 m²

We know that only 0.9 kW/m² reaches Earth so:

P = 0.9\frac{kW}{m^{2}}(1.65)m^{2}

P = 1.485 x 10³ W

Watts is an unit of Power and it can also be written as J/s.

An hour has 3600s or 3.6 x 10³s, so:

E = 1.485 x 10³ \frac{J}{s}(3.6 x 10³s)

E = 5.346 x 10⁶ J

Mega is equal to 10⁶, then:

E = 5.35 MJ

A 1.1 m by 1.5 m window collects, during 1 hour of daylight, 5.35 MJ
