Answer:
The acceleration is 10 m/s²
Explanation:
The question seeks to show the relationship between force, mass and acceleration. Hence, the formula to be used here is that of force which is shown below
F = ma
where F is the force (800 N)
m is the mass (80 kg)
a is the acceleration (unknown)
From the formula above (Force = mass multiplied by acceleration)
800 N = 80 kg × a
a = 800 ÷ 80
a = 10 m/s²
Answer:
Explanation:
Hi!
We define the point (0,0) as the intial position of the ball. The initial velocity is
The motion of the ball in the horizontal direction (x) has constant velocity, because there is no force in that direction. :
In the vertical direction (y), there is the downward acceleration g of gravity:
(note the minus sign of acceleration, because it points in the negative y-direction)
When the ball hits the ground, at t = 65s, y(t = 65 s) = 0. We use this to find the value of the initial vertical velocity:
We used that g = 9.8 m/s²
To find the horizonttal component we use the angle:
Answer:
Mass is how much matter an object contains. Mass and weight are different measurements, although they may seem similar. Mass is measured by comparing one object to another object of known mass. Grams and kilograms are units we use to measure mass.
