Answer 3

Problem Analysis

The problem states that a body is thrown vertically upwards with a velocity of 50 cm/s, and we need to find the distance it travels in 4 seconds.

Solution

To solve this problem, we can use the following kinematic equation to find the displacement of the body:

s = ut + (1/2)at^2

Where: - s = displacement - u = initial velocity - t = time - a = acceleration

Given: - Initial velocity, u = 50 cm/s - Time, t = 4 s - Acceleration due to gravity, a = -9.8 m/s^2 (negative because it acts in the opposite direction to the motion)

Calculation

Substitute the given values into the equation: s = (50 cm/s * 4 s) + (1/2)(-9.8 m/s^2)(4 s)^2

Converting the initial velocity to m/s: 50 cm/s = 0.5 m/s

Now, calculate the displacement: s = (0.5 m/s * 4 s) + (1/2)(-9.8 m/s^2)(4 s)^2

s = (2 m) + (1/2)(-9.8 m/s^2)(16 s^2)

s = 2 m - 78.4 m

s = -76.4 m

Answer

The body will travel a distance of -76.4 meters in 4 seconds.
