What is the momentum of a 800 kg car traveling at 20 m/s
BabaBlast [244]

<u>Answer:</u> The momentum of the car is 16000 kg.m/s

<u>Explanation:</u>

Momentum is defined as the force that keeps the object moving. It is also defined as the product of mass and velocity of an object.

Mathematically,

p=m\times v

where,

p = momentum of the car = ?

m = mass of the car = 800 kg

v = velocity of the car = 20 m/s

Putting values in above equation, we get:

p=800kg\times 20m/s\\\\p=16000kg.m/s

Hence, the momentum of the car is 16000 kg.m/s

A dynamite blast at a quarry launches a rock straight upward, and 1.7 s later it is rising at a rate of 17 m/s. Assuming air res
Shtirlitz [24]

Answer:

(a) v_0= 34m/s

(b) v=14m/s

Explanation:

We can derive the initial speed of the rock from the equation of the speed in function of the time:

v=v_0-gt\\\\\implies v_0=v+gt

Using the given values for the speed at time t=1.7s, we get:

v_0=17m/s+(9.8m/s^{2})(1.7s)=34m/s

In words, the speed of the rock at launch is 34m/s (a).

Next, we use this to calculate the speed at t=4.9s:

v=v_0-gt\\\\v= 34m/s-(9.8m/s^{2})(4.9s)=-14m/s

This means that the speed of the rock at 4.9s after the launch is 14m/s (b), and the negative sign means that it is moving downwards.
