Answer:
Time taken by Jesse to bring his bicycle =5.4 Sec
Explanation:
acceleration of bicycle = -2.5 m/sec²
Initial velocity of by cycle u =13.5 m/sec,
final velocity of bicycle v = 0 (since bicycle completely stop finally)
Let the time taken to stop the bicycle completely = t sec
We now by equation of motion,
putting the value of u,v & a in the equation
0=13.5 -2.5 x t ( a is taken as negative since velocity of bicycle is reducing)
= 5.4 Sec
Answer:
if the weight of the object is equal to the force applied, there will be no change
if the force applied is less than the weight of the object, there won't be any change
if the force application ed is greater than the weight of the object, than the object will move.
Explanation:
here the weight referred to the force of the object.
Recall that work is the amount of energy transferred to an object when it experiences a displacement and is acted upon by an external force. It is given a symbol of W and is measured in joules (J).
W=\vec{F}\cdot \Delta \vec{d}
We can use this formula to determine the work done by very specific forces, generating specific types of energy. We will examine three types of energy in this activity: gravitational potential, kinetic, and thermal. Before we start deriving equations for gravitational potential energy and kinetic energy, we should note that since work is the transfer and/or transformation of energy, we can also write its symbol as \Delta E.

Hope this helped have a nice day
Type one space between the number and the units, and then enter the units in the correct format. For example, a velocity would be entered as "1.2 m/s", not "1.2m/s".
<h3>What is velocity?</h3>
The pace at which an object's direction changes when it is traveling is referred to as its velocity and is measured by a particular unit of time and from a particular point of view. Velocity is a fundamental concept in kinematics, the branch of classical mechanics that deals with the motion of bodies.
<h3>What is an example of velocity?</h3>
Velocity can be defined as the rate at which something moves in a specific direction. as the speed of a car driving north on a highway or the pace at which a rocket takes off.
