A body moving along a straight line at 40m/s undergoes an acceleration of 4m/s2 . after 10 s its speed will be?
Most Upvoted Answer
A body moving along a straight line at 40m/s undergoes an acceleration...
Calculation of Speed
Given
- Initial speed, u = 40 m/s
- Acceleration, a = 4 m/s^2
- Time, t = 10 s
Formula
The formula used to calculate speed is:
Final speed, v = u + at
Calculation
Substituting the given values in the formula, we get:
v = 40 + (4 x 10)
v = 80 m/s
Explanation
The body is moving along a straight line with an initial speed of 40 m/s. It undergoes an acceleration of 4 m/s^2 for a duration of 10 seconds. Using the formula for speed, we can calculate the final speed of the body after 10 seconds. The formula takes into account the initial speed, acceleration, and time taken to determine the final speed of the body. In this case, the final speed is 80 m/s, which means the body has increased its speed by 40 m/s due to the acceleration.

A body moving along a straight line at 40m/s undergoes an acceleration...
V= u +at u= 40m/s a=4m/s t=10s v= 40+(4×10) =40+40 =80 final velocity = 80m/s hope that helps :)
