Speed: A block lies on a horizontal frictionless surface. A horizontal force of 100 N is applied to the block, giving rise to an acceleration of 3 m/s2. What is the speed of the block after 10s?
I think I would just multiple the two and put it in terms of speed but I am not sure.
V = Vo + a*t =
Vo = 0
a = 3m/s^2
t = 10 s.
Solve for V.
To find the speed of the block after 10 seconds, you can use the equation of motion:
v = u + at
where:
v = final velocity (speed)
u = initial velocity (speed)
a = acceleration
t = time
Given:
u = 0 m/s (since the block starts from rest)
a = 3 m/s²
t = 10 s
To find the final velocity, substitute the given values into the equation:
v = 0 + 3 * 10
v = 30 m/s
Therefore, the speed of the block after 10 seconds is 30 m/s.
