Steel materials produce less vibrations whilst less dense and more malleable parts produce more vibrations, e.g. the wooden part of the coaster itself.

Find mass when kinetic energy is 1.6 J and velocity is 0.2 m/s

klio [65]

Answer:

4kg

Explanation:

Given parameters:

Kinetic energy = 1.6J

Velocity = 0.2m/s

Unknown:

Mass of the body = ?

Solution:

The kinetic energy of a body is the energy due to the motion of the body.

It is mathematically expressed as;

Kinetic energy = $\frac{1}{2}$ m v²

m is the mass

v is the velocity

1.6 = $\frac{1}{2}$ x 0.2 x v²

1.6 = 0.1v²

v² = 16

v = 4kg

PLS ANSWER FAST WILL GIVE BRAINLEST!!!

dexar [7]

Answer:

2500 Newtons

Explanation:

If force equals the mass × acceleration then all should be quite simple

25kg is the mass of your car

100 m/s/s is the acceleration of you car

25kg • 100m/s/s = 2500 Newtons
