Assuming that the car skidded to a stop with a constant acceleration of -6 m/s^2, determine the speed of the car in km/h (to one decimal place) before it began to skid.arrow_forwardA bicycle moves along a straight road such that its speed is described by the continuous function f(t). You are asked to determine the magnitude of the displacement of the bicycle between 5.1 and 21 seconds. To do this, you must solve the integral below. What should the bounds on the integral be? Write your answer to one decimal place. As - fo f(t)dt a = Number b = Number seconds secondsarrow_forward
- During a short interval of time, the speed v (in m/s) of a motorcycle is given by the following equation: v=at² + bt³ Assuming time t is expressed in seconds, what are the units of a and b, respectively? O O s³ and b a = m and b = and b= a = m. a= a= 927 and b none of these = m² m 34 m. 8²arrow_forwardWhen an appliance whose power usage is X watts is run for Y seconds, it uses X x Y joules of energy. The energy unit used by electrical utilities in their monthly bills is the kilowatt-hour(kWh, that is,1 kilowatt is used for 1 hour.) How many joules are there in a kilowatt-hour? If electricity costs $0.09 per kilowatt-hour, how much does it cost per megajoule?arrow_forwardA motorcycle starts from rest at s = 0 and travels along a straight road with the speed shown by the v –t graph.
