Answer:
mass and distance
Explanation:
force is mass while motion can also be regard as distance or movement
Answer:
The total work done will be zero.
Explanation:
Given that,
Mass = 100 kg
Force = 392 N
Velocity = 20 m/s
Distance s= 10 m
We need to calculate the work done
Using balance equation
The net force will be



The net force is zero.
Hence, The total work done will be zero by all forces on the object.
The bicycle is a distance <em>x</em> away from the wall at time <em>t</em> according to
<em>x</em> = 10 m + (4 m/s) <em>t</em> + 1/2 (12 m/s²) <em>t</em> ²
so that after <em>t</em> = 8 s, it will be
<em>x</em> = 10 m + (4 m/s) (8 s) + 1/2 (12 m/s²) (8 s)² = 426 m
away from the wall.
Answer:
When he weight of the car is 8.55 x
N then power = 314.012 KW
When he weight of the car is 1.10 x
N then power = 43.76 KW
Explanation:
Given that
Initial velocity
= 0
Final velocity
= 24.8 
Time = 7.88 sec
We know that power required to accelerate the car is given by
P = 
Change in kinetic energy Δ K.E = 
Since Initial velocity
= 0
⇒ Δ K.E = 
⇒ Power P = 
⇒ Power P =
-------- (1)
(a). The weight of the car is 8.55 x
N = 8550 N
Put all the values in above formula
So power P = 
P = 314.012 KW
(b). The weight of the car is 1.10 x
N = 11000 N
Put all the values in equation (1) we get
P = 
P = 43.76 KW
