- After accelerating up to a speed of 20 m/s on his bike, Jim coasts (stops pedaling). Due to air drag he slows down from 20 m/s to 16 m/s in 10 seconds. What is his average acceleration while coasting?arrow_forwardCheetahs can accelerate to a speed of 20.2 m/s in 2.65 s and can continue to accelerate to reach a top speed of 29.0 m/s . Assume the acceleration is constant until the top speed is reached and is zero thereafter. Let the +? direction point in the direction the cheetah runs.Express the cheetah's top speed ?top in miles per hour (mi/h) .Starting from a crouched position, how much time ?accel does it take a cheetah to reach its top speed and what distance ? does it travel in that time?arrow_forwardYour new Telsa Model 3 specs say that it can do 0-60 mph in 3.2 seconds. Can you get the acceleration in SI units based on these numbers? Is the acceleration you get is likely a constant or an average acceleration?arrow_forward
- A car slows from 48.4 kph to 34.9 kph to get off the highway in a span of 8.5 seconds. What is the car’s acceleration, in units of m/s^2 during that time?arrow_forwardA ball is thrown straight down at 1.29 m/s and hits the ground 1.07 seconds later. How many meters did the ball travel before hitting the ground? Type your answer.arrow_forwardYou purchase a used car. After handing over the cash, you drive it away from the lot, starting at rest and accelerating at 19.8 m/s2. After 16.9 s, the engine breaks down and it decelerates at 5.9 m/s2 until coming to a stop. How far were you able to drive the car? (Please answer down to the fourth decimal place- i.e 10.3456)arrow_forward
- A woman backs her van out of her parking space with a constant acceleration of 1.8 m/s2. Assume that her initial motion is in the positive direction. Part A: How long does it take her to reach a speed of 2.1 m/s in seconds? Part B: If she then brakes to a stop in 0.65 s, what is her acceleration in meters per square second?arrow_forwardWhat is the unit for acceleration? A race car accelerates uniformly from 18.5 m/s to 46.1 m/s in 2.47 seconds. Determine the acceleration of the car. A blue beetle starts from rest and in 4.5 seconds is flying 2.2 m/s. What is the acceleration of this insect?arrow_forwardA drag racer crosses the finish line, and the driver deploys a parachute and applies the breaks to slow down. The driver begins slowing down at 6 seconds and the velocity becomes 28m/s. When the time changes to 12 second, the velocity has been reduced to 12.5 m/s. What is the average acceleration of the dragster?arrow_forward
- Eg: A starts with an initial velocity of 10m/s and decelerates at -2 m/s^2. After comes to a full stop, it accelerates with an acceleration of 2 m/s^2 until it reaches 20 m. What is the average velocity in the entire trip?arrow_forwardThe acceleration of an object (in m/s2) is given by the function a(t)=8sin(t)a(t)=8sin(t). The initial velocity of the object is v(0)=−10v(0)=-10 m/s. Round your answers to four decimal places.a) Find an equation v(t) for the object velocity.v(t)v(t) = −8cos(t)−2Correct b) Find the object's displacement (in meters) from time 0 to time 3.3.4187Incorrect metersc) Find the total distance traveled by the object from time 0 to time 3. metersarrow_forwardA car is traveling at a steady 81 km/h in a 50 km/h zone. A police motorcycle takes off at the instant the car passes it, accelerating at a steady 8.4 m/s2 . How much time elapses before the motorcycle is moving as fast as the car?arrow_forward
