Answer:

Time taken to reach final velocity = 5.5 second

Explanation:

Given:

Initial velocity (Starting from rest)(u) = 0 m/s

Acceleration of ball (a) = 1 m/s²

Final velocity (v) = 5.5 m/s

Find:

Time taken to reach final velocity

Computation:

Using first equation of motion;

v = u + at

where,

v = final velocity

u = initial velocity

a = acceleration

t = time taken

5.5 = 0 + (1)(t)

5.5 = t

Time taken to reach final velocity = 5.5 second

A mule is harnessed to a sled having a mass of 246 kg, including supplies. The mule must exert a force exceeding 1210 N at an an
zimovet [89]

(a) 1800 N

The equation of the forces along the vertical direction is:

F sin \theta + N - mg = 0

where

F sin \theta is the component of the applied force along the vertical direction

N is the normal force on the sled

mg is the weight of the sled

Substituting:

F = 1210 N

m = 246 kg

\theta = 30.3^{\circ}

We find N:

N=mg-F sin \theta = (246)(9.8)-(1210)(sin 30.3^{\circ})=1800 N

(b) 0.580

The equation of the forces along the horizontal direction is:

F cos \theta - \mu_s N = 0

where

F cos \theta is the horizontal component of the push applied by the mule

\mu_s N is the static frictional force

Substituting:

F = 1210 N

N = 1800 N

\theta = 30.3^{\circ}

We find \mu_s, the coefficient of static friction:

\mu_s = \frac{F cos \theta}{N}=\frac{(1210)(cos 30.3^{\circ})}{1800}=0.580

(c) 522 N

In this case, the force exerted by the mule is

F= 6.05 \cdot 10^2 N = 605 N

So now the equation of the forces along the horizontal direction can be written as

F cos \theta - F_f = 0

where

\theta=30.3^{\circ}

and F_f is the new frictional force, which is different from part (b) (because the value of the force of friction ranges from zero to the maximum value \mu N, depending on how much force is applied in the opposite direction)

Solving the equation,

F_f = F cos \theta = (605)(cos 30.3^{\circ})=522 N
