একটি গাড়ির বেগ ১৫ মি./সে. থেকে সুষমভাবে বৃদ্ধি পেয়ে ১০ সে. পর ৭৫ মি./সে. হলে গাড়িটির ত্বরণ কত মি./সে.^২?
To solve this problem, let's analyze it step-by-step:

Step-1: we know, acceleration a = dv/dt, where dv = change in velocity, dt = time over which the change occurs

Step-2: So, The initial velocity 15 meters per second.

Step-3: The final velocity is 75 meter per second.

Step-4:  So change in velocity,dv is = (75-15) meter per second = 60 meters per second.

Step-5: Given time period dt = 10 second. So a = dv/dt = 60/10 = 6 meter per second square
#Answer: 6 meter per second square
