Answer:
Explanation:
Given
initial velocity
Distance traveled before stopping
using equation of
where v=final velocity
u=initial Velocity
a=acceleration
s=displacement
v=0 as car stops after travelling
negative sign indicates it is deceleration
What is the acceleration of a car that goes from 0 to 20m/s in 7 seconds?

Answer:
c = 4,444.44
Explanation:
You have the following expression for the acceleration of the projectile:
(1)
s: distance to the ground of the projectile
To find the value of the constant c you use the following formula:
(2)
vo: initial velocity = 0 m/s
v: final speed = 200 m/s
Δs: distance traveled by the projectile = 3m - 1.5m = 1.5m
You replace the expression (1) into the expression (2):
You do the constant c in the last equation, then you replace the values of v, s and Δs:
