Speed simply means a scalar quantity that is used to denote how fast a particular object is moving.

<h3>What is speed?</h3>

Your information is incomplete. Therefore, an overview of speed will be given. Speed simply means the rate at which something moves.

The speed of an object is the magnitude of change of its position with time. The speed of an object is calculated as the distance divided by the time taken.

Marat540 [252]

Answer:

3.69 m/s

Explanation:

Forces :

mgsin Θ - mumgcosΘ = ma

g x sinΘ - mu x g x cosΘ = a

9.8 x sin 21 - 0.53 x 9.8 x cos 21 = a

a = -1.337 m/s²

so you have final velocity = 0 m/s

initial velocity = ? m/s

Given d = 5.1 m

By kinematics

vf² = vo² + 2ad

0 = vo² + 2 x -1.337*5.1

vo = 3.69 m/s

Mary has a mass of 40 kg and sprints at 1 m/s. How much kinetic energy does she have?

Sav [38]

Answer:

20 J

Explanation:

Kinetic energy is given as half of the product of mass and the square of velocity of an object:

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

where m = mass = 40 kg

v = velocity = 1 m/s

Hence, Mary's kinetic energy is:

KE = $\frac{1}{2} * 40 * 1^2$

KE = 20 * 1 = 20 J

She has a kinetic energy of 20 J.
