A ball of mass 1.200 kg is attached to a 0.700 m long string. It is moving horizontally in a clockwise direction, 4.000 m above

ground, with a speed of 20.00 m/s. The centripetal acceleration of the ball is:

Answer:

The ball is making a circular motion. The centripetal acceleration in a circular motion is

a = \frac{v^2}{r}

a = \frac{20^2}{0.7} = \frac{400}{0.7} = 571.4~ m/s^2~

Explanation:

Normally in physics questions like this, we use all the information in the question. Here, we left out the mass or the height of the object. I assume there is more sub-questions that is not shared here. However, the centripetal acceleration can be found by using the velocity and the radius only.

A 5 kg object moving to the right at 4 m/s collides inelastically with a 5 kg object
skad [1K]

Answer:

The linear momentum of a particle with mass m moving with velocity v is defined as

p = mv (7.1)

Linear momentum is a vector . When giving the linear momentum of a particle you must

specify its magnitude and direction. We can see from the definition that its units must be

kg·m

s

. Oddly enough, this combination of SI units does not have a commonly–used named so

we leave it as kg·m

s

!

The momentum of a particle is related to the net force on that particle in a simple way;

since the mass of a particle remains constant, if we take the time derivative of a particle’s

momentum we find

dp

dt = m

dv

dt = ma = Fnet

so that

Fnet =

dp

dt (7.2)

The driver of a 2.0 × 10³ kg red car traveling on the highway at 45m/s slams on his brakes to avoid striking a second yellow car
nignag [31]

Answer:

Explanation:

a = F/m = 7500/2000 = 3.75 m/s²

v² = u² + 2as

s = (v² - u²) / 2a

s = (0² - 45²) / (2(-3.75))

s = 270 m
