Answer:
9.495 m/s
Explanation:
initial horizontal speed, ux = 2.60 m/s
initial vertical speed, uy = 0
height, h = 4.60 m
acceleration due to gravity, g = 9.8 m/s^2
Let the speed of fish is v as it hits the water level.
Use third equation of motion in vertical direction
v = 9.495 m/s
Thus, the fish hits the water level with the speed of 9.495 m/s.
Answer:
4117.65 N
Explanation:
Speed of ball, u = 126 km/h = 35 m/s
Mass of ball, m = 160 g = 0.16 kg
Time interval, t = 1.36 ms = 0.00136 s
We can calculate the force as a measure of the momentum of the ball:
F = P/t
Momentum, P, is given as:
P = mv
Therefore:
F = (mv) / t
F = (0.16 * 35) / (0.00136)
F = 4117.65 N
The force imparted to the two glove d hands of the inexperienced catcher is 4117.65 N.
Answer:
it was made in July 29, 1958, United States
it was founded by
Dwight D. Eisenhower
The first rocket which could fly high enough to get into space was the V2 missile which was first launched by Germany in 1942. The first rocket which actually launched something into space was used to launch Sputnik, the first satellite, on October 4, 1957. The rocket that launched Sputnik was a R-7 ICBM rocket.
