So, Our final answer is 145%
The distance travelled is 10 m
The velocity gained at the end of the time is 2 m/s
<h3>Motion</h3>
From the question, we are to determine distance travelled and the velocity gained
From one of the equations of motion for <u>linear motion</u>, we have that
S = ut + 1/2at²
Where S is the distance
u is the initial velocity
t is the time taken
and a is the acceleration
First, we will calculate the acceleration
Using the formula,
F = ma
Where F is the force
m is the mass
and a is the acceleration
∴ a = F/m
Where F is the force
and a is the acceleration
From the given information,
F = 50 N
m = 250 kg
Putting the parameters into the equation,
a = 50/250
a = 0.2 m/s²
Thus,
From the information,
u = 0 m/s (Since the object was initially at rest)
t = 10 s
S = 0(t) + 1/2(0.2)(10)²
S = 10 m
Hence, the distance travelled is 10 m
For the velocity
Using the formula,
v = u + at
Where v is the velocity
v = 0 + 0.2×10
v = 2 m/s
Hence, the velocity gained at the end of the time is 2 m/s

Answer:
45
Step-by-step explanation:
by the definition of an isocoles triangle, defined by having two congruent sides, (p-s, r-s), angles SPR and SRP are congruent. by the triangle sum theorem, (internal angles + to 180˚) 90˚ + 2a = 180˚. 2a =90, a = 45
Answer:
Jada saved $40, Lin saved $60 and Elena saves $20
Step-by-step explanation:
Let the amount saved by Jada be x
Let the amount saved by Lin be y
Let the amount saved by Elena be z
If together they saved $120, then x+y+z = $120 ......... 1
If Jada saved $20 less than Lin, then x = y- 20 .....2
If Lin saved 3 times as much money as Elena, then y = 3z ...... 3
From equation 3, z = y/3 ....... 4
substitute equation 2 and 4 into 1;
x+y+z = $120
(y- 20)+ y + y/3 = 120
2y + y/3 - 20 = 120
2y + y/3 = 120+20
2y + y/3 = 140
multiply through by 3
6y + y = 420
7y = 420
divided through by 7
7y/7 = 420/7
y = 60
Since y = 3z
60 = 3z
z = 60/3
z = 20
From equation 2, x = y- 20
x = 60-20
x = 40
Hence Jada saved $40, Lin saved $60 and Elena saves $20
