Answer:
Distance = 0.175 km
Explanation:
According to the equation of motion;
Distance covered= Initial velocity*time + 1/2*acceleration*time²
By the given data;
acceleration a = 2 m/s²
initial speed u = 18 km/hr = 18*1000/3600 = 5 m/s
acceleration is uniform
time t = 25 secs
S = u*t + 1/2*a*t²
S = 5*25 + 1/2*2*25²
S = 50+ 125
S = 175 m
S = 0.175 km
