A train travels at 20m/s for 30 seconds. How far has it moved?

600m

Explanation:

We can use the equation speed = distance / time.

We are trying to find the distance, so rearrange to get distance = speed x time.

Substituting in our values, 20m/s x 30s = 600m

Hope this helps, let me know if you have any questions!

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.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
