The table shows information about four students who are running around a track. Which statement is supported by the information

murzikaleks [220]

Answer:

Mohammed has less kinetic energy than Autumn

Explanation:

The kinetic energy of each student is given by:

$K=\frac{1}{2}mv^2$

where

m is the mass of the student

v is the speed of the student

Let's use the formula above to calculate the kinetic energy of each student:

- Autumn: $K=\frac{1}{2}(50 kg)(4 m/s)^2=400 J$

- Mohammed: $K=\frac{1}{2}(57 kg)(3 m/s)^2=256.5 J$

- Lexy: $K=\frac{1}{2}(53 kg)(3 m/s)^2=238.5 J$

- Chiang: $K=\frac{1}{2}(64 kg)(5 m/s)^2=800 J$

Therefore, by looking at the numbers, we see that the correct answer is

Mohammed has less kinetic energy than Autumn

A 5kg baby is asleep in a 5kg stroller. The mom is speed walking in the park at 3m/s. How much momentum does she generate with t

lesya [120]

Answer:

The correct solution is "15 kgm/s". A further explanation is given below.

Explanation:

The given values are:

Mass,

m = 5 kg

Velocity,

v = 3 m/s

By applying the formula of momentum, we get

⇒ $P=m v$

On substituting the given values, we get

⇒ $=5\times 3$

⇒ $=15 \ kgm/s$
