A baseball is thrown vertically downward from the top of a 155 m tower with an initial velocity of -25 m/s. How long will it take, until it reaches the ground?

t = 2.55 s

Explanation:

Given that,

Height from which the baseball is thrown, h = 155 m

Initial velocity of the baseball, u = -25 m/s

We need to find the time taken by it to reach the ground. Let the time is t. Using equation of kinematics to find it as follows:

So, it will take 2.55 seconds to reach the ground.

lol

explanation:

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
