Question

An object starts from rest attaining the speed of 50m/s after travelling a distance of 400m. Find the acceleration of the object.​

Answer 1

Explanation:

required time for the travel 400 metre

$(400 \div 50)s = 8s$

hence the acceleration of the object is

$(50 - 0) \div 8 = 50 \div 8 = 6.25mper \: s {}^{2}$
