Question

b. A racing car has a uniform acceleration of 5 m/s2. What distance will it cover in 15 s after
start?
​

Answer 1

Answer:

562.5m

Step-by-step explanation:

s = ut +½ a ( t*t)

u is 0, t is 15s, a is 5m/s2 , s =?

s = 0*15+ ½ 5 * ( 15*15)

s = 0 + ½ 5*225

s =½ 1125

therefore, 1125 / 2 is 562. 5

thus, answer is 562.5 m
