answer

v = 4.2\frac{m}{s}

set up an equation

we can use the formula for kinetic energy since we know mass and kinetic energy

K = \frac{mv^{2}}{2}

v = \sqrt{\frac{2K}{m} }

values

K = 0.013 J

m = 1.5g = 0.0015 kg

plug in values

v = \sqrt{\frac{2*0.013}{0.0015} }

v = 4.2\frac{m}{s}

A girl of mass 55 kg throws a ball of mass 0.80 kg against a wall. The ball strikes the wall horizontally with a speed of 25 m/s
lisabon 2012 [21]

Answer:

Magnitude of the average force exerted on the wall by the ball is 800N

Explanation:

Given

Contact Time = t = 0.05 seconds

Mass (of ball) = 0.80kg

Initial Velocity = u = 25m/s

Final Velocity = 25m/s

Magnitude of the average force exerted on the wall by the ball is given by;

F = ma

Where m = 0.8kg

a = Average Acceleration

a = (u + v)/t

a = (25 + 25)/0.05

a = 50/0.05

a = 1000m/s²

Average Force = Mass * Average Acceleration

Average Force = 0.8kg * 1000m/s²

Average Force = 800kgm/s²

Average Force = 800N

Hence, the magnitude of the average force exerted on the wall by the ball is 800N
