100 POINTS FOR THE CORRECT ANSWER/ EXPLANATION.
GuDViN [60]

Answer:

d) 15.12 N

e) 15.12 N

Explanation:

Draw a free body diagram of the each block.

Block A has three forces on it: weight force mAg pulling down, normal force N pushing up, and tension force T pulling down.

Block B has two forces on it: weight force mBg pulling down, and tension force T pulling up.

Sum of forces on A in the y direction:

∑F = ma

T + N − mAg = mAa

N = mAa + mAg − T

N = mA (a + g) − T

Sum of forces on B in the y direction:

∑F = ma

T − mBg = mBa

T = mBa + mBg

T = mB (a + g)

Plug in values:

T = (1.80 kg) (-1.60 m/s² + 10 m/s²)

T = 15.12 N

N = (3.60 kg) (-1.60 m/s² + 10 m/s²) − 15.12 N

N = 15.12 N

So the answers to (d) and (e) are both 15.12 N.

6. What is the mass of a boy who is standing on top of a 1.5 meter high
puteri [66]

Answer:

m = 50 [kg]

Explanation:

The potential energy can be calculated by means of the following equation.

E_{p}=m*g*h

where:

Ep = potential energy = 735 [J]

m = mass [kg]

g = gravity acceleration = 9.81 [m/s²]

h = elevation = 1.5 [m]

Now replacing:

735=m*9.81*1.5\\m = 50 [kg]

When you run around a track at 5 km/h, your velocity is constant.
Nat2105 [25]
No it isn't.  Speed and direction are both components of velocity. 
When you run around the track at 5 km/hr, although your speed is
constant, your direction keeps changing, so your velocity does too.
