The most effective activity he can do to maintain his stem ninja without further injury is swimming.
Swimming is a resistance exercise, similar to weight-lifting. However; unlike weight-lifting, swimming places almost no stress on your joints and bones. Therefore; not only does swimming work the muscles but it doesn't have some of the negative impacts that lifting weights has.

Explanation:
take coordinate system correctly. use formulas of projectile motion
Answer: E = 1.93×10^-7 J
Explanation: The formulae for getting the energy stored in a capacitor is given as
E =Cv²/2
Where E = energy stored in capacitor (joules), C = capacitance of capacitor (farad), v = applied voltage =150v.
The formulae implies that we need to get the capacitance of the capacitor (C) first before we can get the energy.
From the parameters given to us
Area of plates =A = 87.5cm² = 87.5/10000 = 0.00875m²
Distance between plates = d = 4.50mm = 4.50/1000 = 0.0045m
C = ε0A/d
Where ε0 = permittivity of free space = 8.85×10^-12 F/m
C = 8.85×10^-12 × 0.00875/ 0.0045
C = 7.743×10^-14/0.0045
C = 1.72×10^-11 F.
Recall that E = Cv²/2
E = ( 1.72×10^-11 × 150×150) /2
E = 3.87×10^-7/2
E = 1.93×10^-7 J
Answer:
-1.17 m/s²
Explanation:
Given:
v₀ = 20 mph = 8.94 m/s
v = 0 m/s
t = 7.63 s
Find: a
v = at + v₀
0 m/s = a (7.63 s) + 8.94 m/s
a = -1.17 m/s²
Answer:
Average velocity is said to be equal to the instantaneous velocity when acceleration is zero. When acceleration of an object is equal to zero, there can be no change in speed or direction.
