Answer:

Solution given:

<C=90°

<B=48.7°

a=?

<A=?

b=?

Now

In right angled triangle

<A+<B+<C=180°[Sum of interior angle of a triangle is 180°]

 <A+48.7+90=180°

<A=180-90-48.7

<A=41.3°

again

Sin 48.7=perpendicular/hypotenuse=b/c

b=sin 48.7°×16

b=12

again

Cos 48.7°=base/hypotenuse=a/c

a=Cos 48.7°×c

a=Cos 48.7°×16

a=10.6

So ,answer is:D.m<A=41.3°,a=10.6 and b=12.

In a collision, a 5 kg mass moving at 2m/s transfers all of its momentum to a 1 kg mass. What is the velocity of the 1kg mass af

statuscvo [17]

Answer:
velocity = 10 m/sec in the same direction as the first body did

Explanation:
The momentum of the body can be calculated as follows:
momentum = mass * velocity

For the first body, we have:
mass = 5 kg
velocity = 2 m/sec
momentum = mass * velocity
momentum = 5 * 2 = 10 kg.m/sec

We know that this momentum is transferred completely to the second body

For the second bode, we have:
momentum = 10 Kg.m/sec
mass = 1 kg
momentum = mass * velocity
10 = 1 * velocity
velocity = 10/1
velocity = 10 m/sec

Finally, we should get the direction of the motion:
Both the velocity of the first and second bodies have positive values. Therefore, the second body is moving in the same direction as the first body did.

Hope this helps :)
