Answer:
Factor = 8.77
Explanation:
Fraction of collision with energy greater than or equal to the activation energy can be given by the formula:
R = 8.314 J/mol.K
When Temperature = 34⁰C = 34 + 273 = 307 K
When Temperature = 52⁰C = 52 + 273 = 325 K
Factor = 8.77
The velocity of the teddy bear as it strikes the ground is 7.67 m/s.
<h3>
Velocity of the teddy when it strikes the ground</h3>
The velocity of the teddy when it strikes the ground is calculated from principle of conservation of energy as shown below.
K.E(bottom) = P.E(top)
¹/₂mv² = mgh
v² = 2gh
v = √2gh
where;
- h is height of fall of the teddy
- g is acceleration due to gravity
v = √(2 x 9.8 x 3)
v = 7.67 m/s
Thus, the velocity of the teddy bear as it strikes the ground is 7.67 m/s.
