Question

A bus of mass 6000kg falls off a ledge in 5 second to reach the ground. Calculate (A) Speed of bus while striking the ground (B) Height of the ledge. (take g = 10 m/s2

Answer 1

Answer:

(A) 50 m/s

(B) 125 m

Explanation:

• for (A) :- given data:- U = 0 m/s ; g = 10 m/s^2 ; t = 5s ; V=?

1. We know that, V=U+gt | or, V= [0+(10)×(5)] m/s | or, V =50m/s

• for (B) :- given data:- g = 10 m/s^2; t = 5s ; h=?

1. We know that, h = (1/2)(g)(t^2) | or, h = [(1/2)(10){(5)^2}] m | or, h = 125m
