1.A student attaches a string to a puck on a frictionless air table, and pulls with a constant force on the puck. a. Draw the fo
Mrrafil [7]

a)

for the puck :

F = force applied in the direction of pull

N = normal force on the puck in upward direction by the surface of table

W = weight of the puck in down direction due to force of gravity


b)

along the vertical direction , normal force balance the weight of the puck , hence the net force is same as the force of pull F .

so  F = ma                                    where m = mass of puck  , a = acceleration

Fnet = F


c)

since the net force acts in the direction of force of pull F , hence the puck accelerates in the same direction .

A bicyclist, traveling with a constant speed, covers 61.Om in 7.80s.
dybincka [34]

Answer:

<h2>The velocity is 7.82 m/s</h2>

Explanation:

In this problem, we are going to solve for the velocity since what we are given as parameters are:

1. Distance covered s= 61m

2. time taken to cover the distance t= 7.8 secs

we know that the expression for velocity is given as

velocity= distance/time

We then substitute the given data into the formula to solve for velocity.

velocity= 61/7.8

velocity= 7.82 m/s

<h2>The velocity is 7.82 m/s</h2>
