Suppose your car accelerates from rest to 9 m/s in 2 s. Assume that the acceleration is constant in this time interval. A. What

Stolb23 [73]

Answer :

(a) The acceleration of the car is, $4.5m/s^2$

(b) The distance covered by the car is, 9 m

Explanation :

By the 1st equation of motion,

$v=u+at$ ...........(1)

where,

v = final velocity = 9 m/s

u = initial velocity = 0 m/s

t = time = 2 s

a = acceleration of the car = ?

Now put all the given values in the above equation 1, we get:

$9m/s=0m/s+a\times (2s)$

$a=4.5m/s^2$

The acceleration of the car is, $4.5m/s^2$

By the 2nd equation of motion,

$s=ut+\frac{1}{2}at^2$ ...........(2)

where,

s = distance covered by the car = ?

u = initial velocity = 0 m/s

t = time = 2 s

a = acceleration of the car = $4.5m/s^2$

Now put all the given values in the above equation 2, we get:

$s=(0m/s)\times (2s)+\frac{1}{2}\times (4.5m/s^2)\times (2s)^2$

By solving the term, we get:

$s=9m$

The distance covered by the car is, 9 m

The ball is launched with total initial energy Einitial = mgho. When it reaches the bottom of the hoops, it now has a potential

NeX [460]

Answer:

K = m g (h₀ - h_plat)

Explanation:

Let's use energy conservation to solve this problem, write the energy at two points of interest

Initial. Higher

E_initial = m g h₀

Final. Lower

E_end = K + Ep

E_end = ½ m v² + m g h_plat

Energy is conserved

E_initial = E_end

m g h₀ = K + m g h_plat

K = m g (h₀ - h_plat)

If the y component of a vector is 36, and the angle between the vector and the x-axis is 27, what is the magnitude of the vector

statuscvo [17]

Answer:

79.29

Explanation:

Given that,

The y component of a vector, y = 36

The angle between the vector and the x-axis is 27.

We need to find the magnitude of a vector.

Let a and b are x and y component of a vector m. There resultant is R. So,

$R=\sqrt{a^2+b^2}$

Where

$a=c\cos\theta\ \text{and}\ b=c\sin\theta$

We have, b = 36 and θ = 27°

So,

$36=R\sin\theta\\\\R=\dfrac{36}{\sin\theta}\\\\R=\dfrac{36}{\sin(27)}\\R=79.29$

So, the magnitude of the vector is 79.29
