Answer:
= 922N
Explanation:
m = 64kg
v(t) = (3.0 m/s²)t + (0.20 m/s³)t².
t = 4.0s
differentiation of v(t) so the acceleration is given by
using Newton’s second law
F (net) = ΣFg = ma
⇒R - w = ma
R = m(a + g)
= 64 (9.81 + 4.6)
= 922N
The height of the ball is 2.45 m.
To calculate the height of the ball, we use the formula below.
<h3>Formula</h3>
- E = mgh................ Equation 1
Where:
- E = Elastic energy of the spring
- m = mass of the ball
- h = height of the ball
- g = acceleration due to gravity.
make h the subject of the equation
- h = E/mg...............Equation 2
From the question,
Given:
- E = 7.2 J
- m = 0.3 kg
- g = 9.8 m/s²
Substitute these values into equation 2
- h = 7.2/(0.3×9.8)
- h = 7.2/2.94
- h = 2.45 m
Hence, The height of the ball is 2.45 m.

This can be solve by using the formula
x = (v^2) (sin 2a) / gwhere v is the intial velocitya is the angle of trajectoryg is the acceleration due to gravity (9.8 m/s2)
x = (15.5^2) (sin 2(34) / 9.8x = 22.73 m
