A powerful motorcycle can produce an acceleration of 3.00 m/s2 while traveling at 90.0 km/h. At that speed the forces resisting

nata0808 [166]

Answer:

1185 N

Explanation:

From Newton’s second law of motion,

F=ma where m= mass of motorcycle, a is acceleration of the motorcycle and F=Force

Net force acting on motorcycle $F_{net}$ is given by $F_{net}=F-f$

Where F is force acting on motorcycle and f is frictional force

Substituting F-f for $F_{net}$

$F_{net}=ma$ hence ma= F- f Substituting a with 3, m with 245Kg and f with 450N as provided

245*3= F- 450

F=245*3 +450= 1185 N

Q25) A room whose length is 10 m and its width is 8 m, using ceramic as its floor. The size of the

mariarad [96]

Answer:

2000 pieces

Explanation:

The number of tiles is given by dividing the area of room by the area of each tile. In this case,

thw areas are as shown below

Area of room is 8*10= 80 m2

Converting dimensions of tiles from cm to m then

Area of tiles is 0.2*0.2= 0.04 m2

No of tiles is 80/0.04=2000 tiles

Consider the following system, where F = 80 N, m = 1 kg, and M = 11 kg M m F What is the magnitude of the force with which one b

Lorico [155]

Answer:

Force exerted by the lighter block on the heavier block is 6.63 N

Explanation:

Given Data

F = 80N

m = 1kg

M = 11kg

Solution:

*We assume that there is no friction

Calculating the acceleration of the system

a = $\frac{F}{m+M}$

a = $\frac{80}{1+11}$

a = $\frac{80}{12}$

a = 6.67m $s^{-2}$

Let's write the Equation of Motion of the heavier block

$F_{1}$ = F - $F_{2}$

Ma = F - $F_{2}$

force exerted by the lighter block on the heavier block is calculated as

$F_{2}$ = F - Ma

$F_{2}$ = 80 - (11 x 6.67)

$F_{2}$ = 6.63 N
