Answer:
Range, R = 5090.1 meters
Explanation:
It is given that,
Velocity of cannon, v = 240 m/s
A cannon is shot at a 30 degree angle above the horizontal. The range of this shot is given by the formula as follows :
g = acceleration due to gravity
R = 5090.1 meters
So, the range of this shot is 5090.1 meters. Hence, this is the required solution.
You answer should be C sorry if I’m wrong
PHYSICS
mass = 55 kg
gravitation earth = 9,8 m/s²
gravitation moon = 1,62 m/s²
Weight Change = ______?
Answer :
1) Earth
w = 55 × 9,8
w = 539 N
2) Moon
w = 55 × 1,62
w = 89.1 N
Answer:
The final speed of the bicyclist is 15.44 m/s.
Explanation:
Given;
initial velocity, u = 0
time of motion, t = 4.8 s
distance covered, d = 37.0 m
The acceleration of the bicyclist is calculated as;
d = ut + ¹/₂at²
37 = 0 + ¹/₂(4.8)²a
37 = 11.52a
a = 37 / 11.5
a = 3.22 m/s²
The final speed of the bicyclist is given as;
v² = u² + 2ad
v² = 0 + 2(3.22)(37)
v² = 238.28
v = √238.28
v = 15.44 m/s
Therefore, the final speed of the bicyclist is 15.44 m/s.
