Well the heat that is needed to raise the temperature of 10g of water by 17oC is 7
Answer:
85.66m
Explanation:
Given the following data;
Horizontal velocity = 25.8m/s
Height = 54m
Initial velocity = 0
We would first of all, solve for the time taken using the formula for maximum height of a projectile.
H = ½gt²
Where;
- H is the maximum height measured in meters.
- g represents the acceleration due to gravity measured in meters per seconds square.
- t represents the time taken measured in seconds.
We know that acceleration due to gravity is 9.8m/s²
Substituting into the equation
54 = ½*9.8t²
54 = 4.9t²
t² = 54/4.9
t² = 11.02
t = 3.32 secs
To find the distance;
Distance, x = velocity * time
x = vt
Substituting into the equation, we have;
x = 25.8*3.32
x = 85.66m
