A rifle fires a bullet at a target. The speed of the bullet is 600m/s. The target is located 400m away. How long does it take fo
1 answer:
0.67s
Explanation:
Given parameters:
Speed of bullet = 600m/s
Distance of target = 400m
Unknown:
Time taken for bullet to reach target = ?
Solution:
Speed is a physical quantity that expresses the rate of change of distance with time;
Speed =
Since time is unknown, we make it the subject of the expression;
time = =
time = 0.67s

Answer:
T = 5.36 s
Explanation:
given,
depth of the mine shaft = 122.5 m
speed of the sound = 340 m/s
time taken = ?
time taken by the stone to reach at the bottom
using equation of motion
initial speed , u = 0 m/s
t = 5 s
time taken by the sound to travel
d =v x t
t = 0.36 s
total time taken for the sound to reach carol after dropping the stone
T = 5 + 0.36
T = 5.36 s
Answer:
4950 meters
Explanation:
Recall that the formula for the speed (v) is given by the quotient of the distance traveled (d) divided by the time (t) it took to cover that distance:
Therefore, for this case in which the car travels at 55 m/s for 90 seconds, we can replace these values in the formula, and solve for the distance covered:
