A 2 kg toy car is held at a height of 3.75 m above the floor.
Calculate the Joules of work done on or by the object in? (I would like to know the steps so if I see another type of question I know each step)
Solution:
Given:
mass (m) = 2 kg
Height (h) = 3.75 m
Since, Work done on the object = gravitational Potential energy stored in the object
Thus : Work done on the object = m g h = (2 kg)(9.81 m/s2)(3.75 m) = 73.58 Joules
Here, g is acceleration due to gravity = 9.81 m/s2
A basketball leaves a player's hands at a height of 2.10 m above the floor. The basket is 3.05 m above the floor. The player likes to shoot the ball at a 36.0 ∘ angle. If the shot is made from a horizontal distance of 7.60 m and must be accurate to ±0.22m (horizontally), what is the range of initial speeds allowed to make the basket? vmin, vmax = ______ m/s Express your answers using thre significant figures separated by...
You carry a 2.20 kg bag of groceries at a height of 0.600 m above the level floor at a constant velocity of 1.10 m/s across a room that is 1.70 m long. Find the total work done on the groceries during the process.
A 350 kg box is pulled 6.40 m up a 30 degree inclined plane by an external force of 5000 N that acts parallel to the frictionless plane. A) Calculate the work done by the external force. Answer in kJ. B) Calculate the work done by gravity. Answer in kJ. C) Calculate the work done by the normal force. Answer in J.

A .1 kg toy car with 0.01 kg, 0.01 m radius solid wheels is pushed into a spring with a 1 N/m spring constant until it has compressed by 0.02 m. The toy car is then released, after which it rolls without slipping on level ground. It is still attached to the spring, so its motion is harmonic (back and forth) motion. a. For this part assume that the mass of the wheels is zero: what is the frequency of...
Suppose a 1350-kg elevator car is lifted a distance 41 m by its cable at a constant speed, assuming the frictional force on the elevator has a constant value of 1575 N. Calculate the work done on the elevator by its cable, in joules. Calculate the work done by the gravitational force on the elevator, in joules, during this process. Calculate the total work done on the elevator, in joules.
Two objects with masses 5.10 kg and 2.10 kg hang 0.700 m above the floor from the ends of a cord 6.60 m long passing over a frictionless pulley. Both objects start from rest. Find the maximum height reached by the 2.10 kg object. Thanks.
2. A toy car has a mass of 0.400 kg. It gets thrown at 9.0 m/s toward a spring-held block with a mass of 1.1 kg. As a result of the impact, the car bounces backward from the block. It does not stick. The block compresses the spring by a maximum distance of 24 cm. After it bounces, the car is traveling 1/3 as fast as it was before it hit the block. It does not stick What is the...
