Answer:

196 N

Explanation:

The weight of an object is given by

$W=mg$

where m is the mass of the object, and g is the gravitational acceleration on the planet.

In this example, we have an object with mass m=20 kg, and the value of the acceleration due to gravity on Earth is g=9.81 m/s^2, therefore if we use the above equation we find the weight of the cannonball:

$W=mg=(20 kg)(9.8 m/s^2)=196 N$

Firdavs [7]

Answer:

The truck's speed is 4.04 m/s.

Explanation:

Given that,

Emit frequency = 600 Hz

Beat = 7.00 beat/sec

We need to calculate the truck's speed

Using formula of speed

$\text{frequency observed}=\text{frequency emitted}\times\dfrac{v}{v+v_{source}}$

Where, v = speed of sound

Put the value into the formula

$(600-7)=600\times(\dfrac{343}{343-v_{truck}})$

$v_{truck}=\dfrac{600\times343-593\times343}{593}$

$v_{truck}=4.04\ m/s$

Hence, The truck's speed is 4.04 m/s.

A projectile is fired from a gun near the surface of earth. the initial velocity of the projectile has a vertical component of 9

nadezda [96]

The gravitational acceleration experienced by the bullet due to the earth's gravitational force is approximately equals to 9.81 m/s^2

At maximum point of height, vertical component of velocity equals to zero because it experiences a pause momentarily before coming back down.

Since -acceleration=(Final velocity-initial velocity) divided by time. Taking upwards to be positive, time taken= 10s
