Answer:
because the car needs gas so why wouldnt it stop working
Explanation:
Answer:
the maximum height reached by the object from where it was launched is 0.4591 m
Explanation:
initial speed of the object, u= 3 m/s
The velocity at the maximum height will always be 0.
Therefore, final velocity, v= 0 m/s
Using the Newton's equation of motion,
v^2 - u^2 = 2*g*h(max)
0 - u^2= 2*g*h(max)
h(max) = -u^2 /2* g
where g is the gravitational acceleration.
g= - 9.8 m/s^2
substituting the values in equation,
h(max)= - (3*3) / 2*(-9.8)
h(max) = 0.4591 m
the maximum height reached by the object from where it was launched is 0.4591 m

1. Answer;
Acceleration is;
-2.46m/s²
Explanation;
The initial velocity is 8.6 m/s, the final velocity = 0 m/s
The time is 3.5 seconds
Using the equation;
V =U + at
but V =0 , -U = at
a = -U/t = -8.6 /3.5
= -2.457 m/s²
= -2.46 m/s² (2 d.p)
2. Answer;
The distance is ;
=15.1 m
Solution;
a = -2.46 m/s², v=0 and U = 8.6 m/s
Using the equation;
V² = U² +2as (where s is the distance)
but v =0, thus, s =U²/2a
= -8.6²/ 2(-2.46)
= -73.96 /-4.92
= 15 .1 m (1 d.p)
