Answer: initial velocity: 20 m/s
time taken to complete the turn: 50s
final velocity: 15 m/s
average acceleration= final velocity-initial velocity/time taken - 0s( 0 is taken here as there was no initial time)
= 15-20/50-0
= -5/50= -0.1 ms^2
Answer:
d
Explanation:
According to me answer is d but gas expand more than others
Answer:
21.59 m/s
Explanation:
recall that one of the equations of motions can be expressed as
v² = u² + 2as
where,
v = final velocity (we are asked to find this)
u = initial velocity = 0m/s (because it says that it starts from rest)
a = acceleration = 3.7m/s²
s = distance travelled = 63 m
simply substitute the known values above into the equation:
v² = u² + 2as
v² = 0² + 2(3.7)(63)
v² = 466.2
v = √466.2
v = 21.59 m/s
