What is the magnitude of the gravitational force acting on an object?

The magnitude of the gravitational force acting on an object is weight

Explanation:

In introductory physics textbook, we can find that weight is nothing but a force applied on a given body, by earth's gravity. It is denoted by the formula as,

                                         W = mg

where 'W' is the weight, 'm', is the body's mass, and 'g', the acceleration due to its gravity. When a ball is thrown high into the air, there is no friction. Friction is eliminated. Now, inertia is just a resistant force to change of motion. Hence, the only possibility is weight.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
