Question

A Car with an Initial Velocity of 60 km /h needs 144m To Come To A Complete Halt. Determine The Acceleration Of The Car. then for the same acceleration, determine the stopping distance of this car with if initial velocity is 30 km/h​

Answer 1

Answer:

acceleration= 0.96

stopping distance=36.1

Explanation:

1). v^2-u^2=2as

(50/3)^2=2a(144)

a= 0.96

2). v^2-u^2=2as

(25/3)^2=2(0.96)s

solving this...we get

: s= 36.1
