Gaaffii 1

A man is standing on a spring scale in an elevator. When the elevator is at rest, the scale reads 560N. When the elevator stars to move, the scale reads 600N. The elevator has

  1. A.An upward acceleration
  2. B.A constant down ward speed
  3. C.A constant upward speed
  4. D.A constant upward speed
Deebii fi ibsa ilaalaa

Deebii: A An upward acceleration

Maaliif

The scale reading represents the normal force (apparent weight). Since the scale reads 600 N, which is greater than the true weight of 560 N, there is a net upward force (N−mg=ma>0N - mg = ma > 0), indicating an upward acceleration.

Gaaffii 2

What is the necessary and sufficient condition for conservation of linear momentum?

  1. A.The presence of more linear than non linear forces in the system.
  2. B.Net force on the system is zero.
  3. C.The presence of only non-linear forces.
  4. D.Internal forces exceed external forces.
Deebii fi ibsa ilaalaa

Deebii: B Net force on the system is zero.

Maaliif

By Newton's second law for a system, the rate of change of total linear momentum equals the net external force (dp⃗dt=F⃗net\frac{d\vec{p}}{dt} = \vec{F}_{\text{net}}). Thus, total linear momentum is conserved if and only if the net external force on the system is zero.

An airplane flies at speed of 720.0 km/hr at 37∘37^\circ North of west direction. How far does the plane travel to the west in 1 hour?

  1. A.432km
  2. B.720km
  3. C.576km
  4. D.504km
Deebii fi ibsa ilaalaa

Deebii: C 576km

Maaliif

The westward component of the velocity is vw=vcos⁡(37∘)=720.0 km/h×0.8=576 km/hv_w = v \cos(37^\circ) = 720.0\text{ km/h} \times 0.8 = 576\text{ km/h}. In 1 hour, the distance traveled westward is 576 km/h×1 h=576 km576\text{ km/h} \times 1\text{ h} = 576\text{ km}.

Determine the torque in Nm due to a force F =(2i � 3j + 4k)N acting at point r=(3i + 2j + 3k)m about the origin?

  1. A.6i ? 6j + 12K
  2. B.-6i + 6j + 12k
  3. C.17i - 6j � 13k
  4. D.-17i + 6j + 13k
Deebii fi ibsa ilaalaa

Deebii: C 17i - 6j � 13k

Maaliif

Torque is given by the cross product τ⃗=r⃗×F⃗\vec{\tau} = \vec{r} \times \vec{F}. Computing the determinant with r⃗=(3,2,3)\vec{r} = (3, 2, 3) and F⃗=(2,−3,4)\vec{F} = (2, -3, 4) yields τx=8−(−9)=17\tau_x = 8 - (-9) = 17, τy=6−12=−6\tau_y = 6 - 12 = -6, and τz=−9−4=−13\tau_z = -9 - 4 = -13, giving 17i^−6j^−13k^ N⋅m17\hat{i} - 6\hat{j} - 13\hat{k}\text{ N}\cdot\text{m}.

An airplane travelled from Addis Ababa to Mekele, 780km in 45minutes. What was it average speed?

  1. A.0.28m/s
  2. B.1040km/hr
  3. C.17.3m/min
  4. D.585km/hr
Deebii fi ibsa ilaalaa

Deebii: B 1040km/hr

Maaliif

The time of travel is 45 minutes=0.75 hours45\text{ minutes} = 0.75\text{ hours}. Average speed is vavg=dt=780 km0.75 h=1040 km/hv_{\text{avg}} = \frac{d}{t} = \frac{780\text{ km}}{0.75\text{ h}} = 1040\text{ km/h}.

Gaaffii 8

An example of a body moving with constant speed but still accelerating is

  1. A.a body moving on a straight road.
  2. B.a body moving on a straight railway track
  3. C.a body moving in a circular path
  4. D.a body falling in a viscous fluid.
Deebii fi ibsa ilaalaa

Deebii: C a body moving in a circular path

Maaliif

A body moving in a circular path at constant speed undergoes centripetal acceleration because the direction of its velocity vector is continuously changing.
